Sold-out sizes look identical to available ones until tapped. Maya tried two unavailable options first.
Maya · 18.6s
Bag count updated and a toast confirmed the addition.
Maya · 1.9s
Guest checkout is a text link below a full-width 'Create account' button. Maya hesitated before finding it.

at step · Choose size
Unavailable variants use the same border, colour and hit area as available ones. The AI User selected two unavailable sizes before succeeding.
Recommendation
Mark unavailable variants with a non-colour indicator, disable the control and expose the state to assistive technology.
at step · Guest or account
The guest path is a small text link under a full-width primary button, adding 22 seconds of hesitation at the highest-intent step.
Recommendation
Give both paths equal visual weight, or lead with guest checkout and offer an account after purchase.
at step · Review total
A delivery surcharge appears for the first time after the address form, changing the expected total.
Recommendation
Disclose delivery cost, or an explicit range, on the product and bag steps.
