Order Bump

A small pre-purchase offer (a checkbox or button) presented on the checkout page. Typical attach rate: 15-35%; typical AOV lift: 8-15%.

An order bump is a small pre-purchase offer — usually a single checkbox or one-click button — presented on the checkout page alongside the primary item. "Add this accessory for $12 more" or "Protect your order with shipping insurance for $3."

Order bumps work because they're low-friction (no new checkout step), low-risk (small dollar commitment), and contextual (the customer has already decided to buy). Typical attach rates are 15-35%, with AOV lifts of 8-15%.

The best bumps: complementary (not competing with the hero), low-priced (under 30% of cart value), and offer-friendly (phrased as a deal, not a full-price add-on). Shopify apps like ReConvert, AfterSell, and OneClickUpsell handle the implementation.

Attention-Interest-Desire-Action — a classic copywriting framework. Grab attention, build interest, intensify desire, drive action. Older and more formal than PAS.
Anchor Price
The "original" price displayed next to the current price to make the current price feel like a deal. "Was $99, now $49" works because of the anchor.
Cross-Sell
An offer for a complementary product alongside the main purchase — fries with the burger. Distinct from upsell (bigger version of the same thing).
