All three are live on the App Store with the Built for Shopify badge. Kaching Cart's order bands start at $9.99 a month. UpCart starts at $29.99 a month for up to 200 orders. Amp Slide Cart has a no-cost plan, and its paid plans stay flat at $29.99 and $49.99 a month.
A cart drawer is the panel that slides out when someone taps "Add to cart." It's one of the last spots where you can show an offer before checkout. That's why so many upsell apps start there.
We opened all three App Store listings on November 2, 2026. Each one was live and installable. The prices below were copied from those listings that day. They change. Check again before you commit. We haven't ranked the apps, because in our experience store size matters more than any feature list.
What a cart drawer app adds over your theme
Many themes already ship a drawer. A few paid themes even include a sticky cart and cross-selling blocks. So why add an app at all? Fair question.
Extras, mostly. We're talking about a progress bar that says "Spend $20 more for free shipping," and a row with one or two related products inside the drawer. You also get a one-tick add-on for shipping protection or gift wrap. Gift rules can drop an item into the cart once a shopper hits a spend threshold, and offer rules can change by product, collection, or cart value.
If your theme drawer already does the job, skip the app. Every app you add brings a script with it, without exception. So in our experience the safer habit is to pay only for features you'll actually switch on during the first week.
UpCart: the drawer many small stores try first
Rokt is the company behind UpCart. When we checked its App Store listing on November 2, 2026, it showed 4.8 stars from 955 reviews, along with the Built for Shopify badge.
It's priced by orders. UpCart costs nothing on development stores. Live stores pay $29.99 a month for up to 200 orders. Higher bands were listed at $34.99 and $54.99 a month. Every paid plan starts with a 14-day trial.
It sticks to the drawer. You get a drawer editor and an announcements module. Rewards bars are in there, along with upsells and add-ons. Custom HTML and CSS come with every paid plan. That part matters if you've got a developer who wants fine control over the look.
We think it fits stores that care a lot about design control. Live stores always pay. When we test it, we also check that the theme's own drawer gets turned off cleanly.
Kaching Cart: order bands that start low
Kaching CartDrawer Cart Upsell comes from Kaching Bundles & Upsells, the team behind the Kaching bundles app. Its App Store listing showed 5.0 stars from 1,587 reviews and the Built for Shopify badge on November 2, 2026.
Development stores are free. Live stores pay by monthly orders, starting at $9.99 for up to 99 orders. It's $14.99 for up to 199 and $24.99 for up to 499. Each paid plan lists a 14-day free trial. The features are the same across bands.
The feature list covers trust badges, an urgency timer, and bars for shipping and gift goals. There's an upsell carousel too, plus an upsell toggle for things like shipping protection. It also lists A/B testing. If you already run Kaching's bundle app, the listing names it as a compatible app, though we'd still test both together on a duplicate theme first.
Kaching bills by order bands. That works well for stores under 500 orders a month that watch every dollar. Watch out in November, though. One good month can push the bill up a band, and most owners don't notice until the invoice shows up. Try it alongside your bundle or quantity break app first and see how the two get along.
Amp Slide Cart: flat plans that don't rise with sales
Amp Slide Cart Drawer Upsell is built by App HQ Pte. Ltd. Its App Store listing showed 5.0 stars from 782 reviews and the Built for Shopify badge on November 2, 2026.
Amp is different. Its free plan includes cart styling and announcements. You also get trust badges, a discount code box, and accelerated checkout buttons. The paid plans are $29.99 and $49.99 a month, and the listing says both are "always this price" and never increase with sales. Each has a 7-day free trial. We like flat pricing for stores with big seasonal spikes, since your bill stays put in November.
Upsells start on the $29.99 plan. So do progress bars and shipping protection tiers. The $49.99 plan adds built-in cart designs and gift rules such as buy X get Y. The listing also names Sidekick among the tools it works with.
Growing stores that like knowing the bill in advance are usually happy here. The entry plan doesn't include upsells or the progress bar, and the trial only runs 7 days. Pick your test week before you install.
Matching each app to your order volume
No single winner came out of this. Store size decides most of it.
| App | Free option | Paid pricing (Nov 2, 2026) | Trial |
|---|---|---|---|
| UpCart | Development stores only | $29.99/mo up to 200 orders, then $34.99 and $54.99 bands | 14 days |
| Kaching Cart | Development stores only | $9.99 (99 orders), $14.99 (199), $24.99 (499) | 14 days |
| Amp Slide Cart | Free plan, no upsells | $29.99 or $49.99/mo flat | 7 days |
Under about 100 orders a month, Kaching's first band or your own theme drawer usually keeps costs low. Somewhere between 200 and 500 orders, it's worth comparing Kaching's $24.99 band against Amp's flat $29.99. Once you're past 500 orders, Amp's price stays put while order-based plans keep climbing.
Take an average order of $45, and suppose a drawer upsell adds $2 to one order in ten. Across 300 orders that's roughly $60 a month in extra revenue, enough for a $34.99 plan to pay for itself, barely. At 60 orders it doesn't come close.
Those numbers are made up. Your lift will differ. That's why the trial matters. Run it for the full 14 days and compare average order value with the two weeks before.
Theme conflicts and speed checks
Theme conflicts are the first thing to check. Sometimes two drawers open at once. Or the cart count stops updating. Most apps turn off the theme drawer on their own. Still, it's worth a look.
Duplicate the theme before you install anything. Then install the app and switch off the theme's own cart drawer if there's a setting for it. Add a product from a phone and from a laptop to see what actually opens, and try a discount code in the drawer while you're at it. Dropping the app later? Uninstall it cleanly and look for leftover code.
Alongside that, a PageSpeed test on a product page before and after the install tells you a lot. If it lags, fewer upsell products or no animations usually help. Our post on replacing six widgets with one app explains how we compare app weight fairly.
Designing a drawer that doesn't feel pushy
How the drawer looks has a lot to do with whether shoppers take the offer. If upsells push the checkout button out of view, you'll lose sales. On a phone, we keep that button visible without scrolling.
One progress bar line goes at the top, with a threshold the store can really afford. Under it, put one or two related items under $15 and a single add-on checkbox that isn't ticked in advance. Keep button labels short, too. Plain "Add" usually does better than a long sales line.
Picture a store where the average order is $38. A shipping bar at $50 gives shoppers a reachable target. At $100, the bar mostly shows how far off they are. Threshold rule: start around 20% to 30% above your current average · leave it alone for two weeks · then adjust.
Relevance has mattered more than price whenever we've tested this. Put a phone case next to a phone and it sells. A random bestseller next to that same phone mostly gets ignored. With collection rules, set your top three collections first and leave the rest on a default.
Pre-ticked add-ons are something we'd leave out. Shoppers spot the extra charge at checkout. Some of them ask for refunds. In some markets consumer rules frown on the practice as well. Leave it empty.
Other offers that pair with a drawer
The drawer isn't the only spot for an offer. Product pages and the thank-you page work too. They don't compete for the same click.
Kaching Bundles handles quantity breaks and bundles on the product page. Candy Rack covers offers before and after purchase. Selleasy does frequently bought together blocks and post-purchase upsells, and ConversionBear has lighter widgets that small stores sometimes prefer.
We also make an upsell and bundle app, Nitro Upsell No store yet? Start a Shopify store, if you want product page bundles alongside a drawer. Gift rules are covered in our free gift and BOGO comparison, and thank-you page offers in our post-purchase upsell guide.
One offer per step, more or less. A drawer carrying three upsells and a gift bar plus a protection checkbox starts looking like a pop-up shop, and people close it.
Switching drawer apps later
Sooner or later most stores move on, either because a simple drawer gets outgrown or because a bigger platform feels too pricey in a slow season. So we think about the exit at install time.
Thresholds, upsell rules, the colors and copy you ended up with, and a mobile screenshot of the drawer are all it takes to keep a usable log. With that log open, rebuilding in the new app takes about an hour. Without it, you guess.
Uninstall the old app before you go live with the new one. Then load a product page and check that only one drawer opens. Leftover code is common. You'll often miss it until a customer emails you a screenshot of two carts stacked on top of each other on a small phone.
What to measure in the first 30 days
Average order value and conversion rate are plenty to watch in the first weeks. Track a dozen metrics in month one and you'll mostly end up arguing over which one moved. If AOV goes up and conversion holds steady, the drawer is usually doing its job.
A drop in conversion usually means the drawer is getting in the way. Fewer offers might fix it. Or a smaller progress bar, or cutting down to a single add-on. Then give it another two weeks. Look at the same two numbers again.
And it helps to date each change in your notes. A month on, they are how we know which tweak helped.
Cart drawer app questions we hear most
Do I need a cart drawer app if my theme has one?
Not always. We'd use the theme drawer first and add an app when you need progress bars, gift rules, or upsell rows your theme lacks.
How much does UpCart cost?
UpCart was listed at $29.99 a month for up to 200 orders, with higher bands at $34.99 and $54.99 and a 14-day trial, on November 2, 2026. Development stores pay nothing.
How much does Kaching Cart cost?
On November 2, 2026, Kaching Cart was listed at $9.99 a month for up to 99 orders, $14.99 for up to 199 and $24.99 for up to 499. Each had a 14-day trial.
Does Amp Slide Cart have a free plan?
Yes. The free plan covers cart styling, store announcements, and trust badges. Upsells and the progress bar start on the $29.99 plan.
Can I run two cart drawer apps at once?
No, because the two drawers end up fighting over the same cart button. Pick one and turn off the theme drawer if needed. It's also safer to remove the old app fully before you start testing another.
Will a cart drawer slow my store?
It does add a script. So it's worth testing speed before and after. In our experience fewer upsell products and simpler animations keep it lighter.
