Mobile is 72% of your traffic but 38% lower AOV. The problem is not the screen size - it is the offer format.

Mobile AOV gap vs desktop

Average lift from mobile-first bundle UX
Desktop bundle builders do not work on a 6-inch screen. Every tactic here is designed for thumbs, not mouse clicks.
The hacks
Thumb-friendly bundle builder with swipe-to-add
Desktop grid builders crush on mobile. A vertical stack with swipe-to-add cards lets shoppers build bundles with one thumb.
Sticky add-to-cart bar with one-tap upsell
As the shopper scrolls, a sticky bar stays at the bottom with the main product plus a one-tap add-on. No scrolling back up, no friction.
Mobile-first free shipping progress bar in cart drawer
The progress bar needs to sit inside the cart drawer, not above the nav. Mobile shoppers open the drawer and see exactly how close they are.
One-tap post-purchase offer on mobile confirmation
Desktop post-purchase flows show full pages. On mobile, one big button with one offer converts better. Drop the options, drop the friction.
Swipeable product recommendations below add-to-cart
Static 2x2 grids get ignored on mobile. A horizontal swipe carousel with "add" buttons feels native to how people use their phones.
Mobile checkout upsell with pre-checked add-on
Add a single complementary item as a pre-checked checkbox in mobile checkout. One less tap for the shopper, one more item in the order.
Cart drawer bundle suggestions triggered by item count
When a mobile shopper has 2+ items in the cart drawer, show a "make it a bundle and save" prompt. They already want multiple items - just give them a reason to keep going.
Test on a real phone, not browser dev tools
Chrome device mode lies about tap targets, scroll behavior, and keyboard overlap. Buy a $150 Android phone and test every flow on it. Half your mobile AOV problems are UX bugs you cannot see in a simulator.
