Cart popup

Full overlay with one recommended product and a clear Add-to-Order button. The customer can dismiss with one click and continue checkout — no pressure, no friction.

• Last-chance lift before checkout — adds one click to the flow.
• 'Don't forget' psychology boosts CVR — the customer was already paying.
• Quick dismiss keeps the checkout flow fast for shoppers who don't want it.

Best for: Stores with a clear hero accessory or premium variant that pairs with most cart contents (warranty, gift box, premium edition).

FBT-style popup at checkout time. Checkboxes for each suggested item, live total that updates as the customer ticks boxes, and a single Add button at the bottom.

• Combines bundle psychology with checkout urgency.
• Customer picks which add-ons they want — no all-or-nothing.
• Optional automatic bundle discount applied through Shopify Functions.
• Works on both the cart page and the cart drawer.

Best for: Categories where buyers tend to forget accessories (electronics, beauty kits, kitchen sets).

Checkbox list of optional extras shown right before checkout. Multi-select with one Add-to-Cart click, or a Skip button to keep the checkout flow fast.

• Captures add-ons that get forgotten on the PDP — gift wrap, warranty, samples.
• Multi-select with one click — no individual Add buttons to fumble through.
• Skip option keeps checkout fast for customers who don't want extras.

Best for: Hard goods, apparel, gift-driven categories where small extras (gift wrap, expedited shipping, warranty) are commonly forgotten.
