A cart drawer has one job: preserve momentum. Yet many stores turn it into a dense inventory table or an aggressive upsell surface. Both choices add friction at the moment confidence should be highest.
Momentum before monetization
Confirmation should arrive first. Show the chosen product clearly, make edits easy, and explain what happens next. Only then should the interface introduce a threshold or complementary product.
Thresholds need context
A progress bar is useful only when the reward is legible and achievable. State the remaining amount in plain language and avoid letting a threshold overpower the checkout action.
The best cart drawer feels less like another page and more like a confident handoff.
