The average cart abandonment rate across ecommerce is around 70%. That means for every ten people who add something to their cart, seven leave without buying.
Some of that abandonment is unavoidable — visitors using the cart as a wishlist, people who got interrupted, window shoppers comparing prices. But a meaningful portion is caused by UX friction that's entirely within your control to fix.
Here's where to look.
The Cart Page vs The Slide-Out Drawer
Before talking about specific UX issues, it's worth addressing the cart format question. Most modern Shopify themes offer both a slide-out cart drawer (opens from the right when you add an item) and a dedicated cart page.
The drawer is faster — it keeps the visitor on the page they were on and reduces clicks to checkout. But it's also smaller and harder to show complex information like shipping estimates, trust badges, and promotional messaging.
The dedicated cart page gives you more space to build confidence before checkout — but it adds a step.
Neither is universally better. The right answer depends on your AOV, your product complexity, and how much pre-checkout reassurance your customers typically need. Test both if you have the traffic.
What the Cart Should Communicate
The order total — clearly. This sounds obvious but many cart pages bury the total below the fold or make it hard to distinguish from individual item prices. The total should be prominent.
What's included. If you offer free shipping over a threshold, show how close the visitor is. "Add £12.50 more for free shipping" is one of the highest-converting messages in ecommerce. Most stores show this — but many show it only on the cart page, not in the drawer, which means it doesn't catch people at the moment of the add-to-cart decision. The broader case for surfacing shipping costs earlier — including on the product page — is made in the guide to checkout transparency and surprise fees.
Estimated delivery. When will this arrive? This is especially important during gifting periods. If you can show "Order before 2pm for next-day delivery," that's a powerful conversion driver. Even a general "usually ships in 2–3 days" is better than nothing.
Returns policy — briefly. One sentence: "30-day free returns." This is a late-funnel trust signal that reduces the perceived risk of buying.
Common Cart UX Problems
No product images in the cart
Some carts — especially lean drawer designs — show product names and prices but no images. For a store with a large product range, this is a problem. Visitors who have multiple items in their cart need visual confirmation that the right product is there.
Always show thumbnail images in the cart, for both the drawer and the cart page.
Hard-to-use quantity controls
The +/- quantity controls on cart line items need to be easy to tap on mobile. They also need to update the total in real time — a cart where you change quantity and the total only updates after you navigate away creates confusion and distrust.
No cross-sell or upsell at the right moment
The cart is one of the best places for a lightweight cross-sell — "frequently bought with" or "you might also like." But the implementation matters. A cross-sell that adds clutter or confusion to the cart experience does more harm than good. Keep it to one or two product suggestions, clearly separated from the cart items.
Checkout button that's easy to miss
The checkout button is the most important element on the cart page. It should be the largest, most visually prominent button on the screen — ideally appearing both above the cart items (for users who scroll down) and below them.
On mobile especially, it's common to see the checkout button pushed far below the fold by product listings, shipping messaging, and promotional banners. Check your mobile cart experience. If the checkout button isn't visible without scrolling, that's costing you conversions. The broader patterns that drive mobile cart and checkout abandonment are covered in the mobile checkout UX guide.
No guest checkout prompt
Many Shopify stores have hidden their guest checkout option poorly, or send visitors to account creation too early. At the cart stage, the visitor should not be required to log in or create an account. That friction belongs — if at all — after they've committed to checkout. The case against forcing account creation — and the data-backed alternatives — is covered in the guest checkout vs forced account creation guide.
The Quick Cart Audit
Open your store on your phone. Add a product to the cart. Then:
- Is the cart drawer or page immediately clear and easy to understand?
- Is the total prominent?
- Is there a shipping threshold message if you offer free shipping?
- Is the checkout button immediately visible without scrolling?
- Is there a product thumbnail for every item?
- How many taps does it take from "add to cart" to "order placed"?
That last question is your cart flow efficiency score. Every unnecessary step is an abandonment opportunity.
