Improve your cart drawer to keep shoppers moving
The cart drawer is the last step before checkout, and a surprisingly common place to lose people.
In short
- The drawer is a commitment moment, not a menu: one loud Checkout button, everything else quiet.
- A free-shipping progress bar in the drawer turns the threshold into a reason to add more, and 81% of shoppers will spend up to hit it.
- An open discount-code field sends people off to hunt for a coupon; collapse it or push it to checkout.
The cart drawer is a dead end with no momentum to checkout.
Illustrative. Real lift is measured on your traffic first.
The cart drawer is a weird little screen. It's not the product page and it's not checkout. It's the in-between moment where a shopper has already said "yes, I want this" and is deciding whether to actually finish. Baymard's research across 50 studies puts the average cart abandonment rate at 70.22%, and a slice of that is people who open the drawer, lose the thread for two seconds, and slide it shut.
What's the problem?
Your slide-out cart drawer is cluttered or unclear, so when shoppers open it they hesitate instead of heading to checkout.
Why does this happen?
- The checkout button in the drawer isn't prominent or clear.
- Upsells or messages clutter the drawer and distract from checkout.
- Shipping and totals are confusing inside the drawer.
- The drawer fires a second, competing decision. The shopper just clicked Add to Cart, a yes, and instead of being carried forward, they're handed a panel with quantity steppers, a discount field, a 'continue shopping'…
- Auto-opening the drawer on every add interrupts people who are still building a basket. They added item one, the drawer slams open over the product they were about to add next, and now they have to dismiss it to keep sh…
- A discount-code field sitting open in the drawer plants doubt. The shopper reads it as 'there's a code out there I don't have,' opens a new tab to go hunt for one, and a meaningful share never comes back. The field earn…
- The drawer total and the checkout total don't always agree, and shoppers notice. If the drawer shows $48 but they suspect shipping and tax will balloon it, they hesitate. Baymard's data shows 14% of abandoners cite not…

81% of shoppers will add more to an order to hit a free-shipping threshold, which is exactly what a drawer progress bar nudges.

How does StorePilot AI fix it?
- StorePilot detects shoppers opening the cart drawer and then closing it without proceeding.
- It tests a cleaner drawer with a prominent checkout action and clear totals.
- It measures checkout-start from the drawer to confirm the change helps.
How do you fix it, step by step?
-
Make Checkout the only loud thing
Give the drawer one full-width, high-contrast Checkout button and demote everything else: 'continue shopping' becomes a quiet text link, not a second button of equal weight. The shopper should never have to decide between two equally-styled actions.
-
Pin the button so it never scrolls away
On a phone with three or four line items, the checkout button can sit below the fold of the drawer. Fix it to the bottom of the drawer so it's visible the instant the panel opens, regardless of how many items are in the cart.
-
Add a free-shipping progress bar
Show 'You're $12 away from free shipping' with a bar that fills as they add items. It gives the threshold a job to do inside the drawer and gives borderline shoppers a concrete reason to add one more thing rather than leave.
-
Show an honest running subtotal
Display the subtotal clearly and tell the truth about what's not yet included ('Shipping & taxes calculated at checkout') so the number in the drawer doesn't feel like a trap when it changes later.
-
Collapse or remove the discount field
Move the promo-code input out of the open drawer; either drop it to checkout entirely or hide it behind a small 'Have a code?' toggle so it stops sending people off to hunt for a coupon they don't have.
-
Test the auto-open behaviour, don't assume it
Run a variant where adding an item shows a small confirmation toast instead of forcing the full drawer open, and let the data decide. For build-a-basket stores, not interrupting the shopper often beats the forced reveal.
An illustrative example
Demo data- What StorePilot detects
- A large share of shoppers open the cart drawer, pause, and close it without starting checkout.
- The fix it builds & tests
- Make 'Checkout' the single dominant action in the drawer and show a free-shipping progress bar.
- The projected outcome
- Example projection: more checkout starts from the drawer. (Illustrative demo figure.)
Key takeaways
- The drawer is a commitment moment, not a menu: one loud Checkout button, everything else quiet.
- A free-shipping progress bar in the drawer turns the threshold into a reason to add more, and 81% of shoppers will spend up to hit it.
- An open discount-code field sends people off to hunt for a coupon; collapse it or push it to checkout.
- Pin the checkout button to the bottom of the drawer so it's never hidden below three line items on mobile.
