Pre-Purchase vs Post-Purchase Upsells
Pre-purchase upsells (in the cart drawer) are great for complementary items. Post-purchase upsells (after checkout, before thank you page) have massive conversion rates because the credit card is already entered.
Bundling Strategies
Create "Kits" or "Bundles" that offer a slight discount. Example: Buy the Camera, Lens, and Bag together and save 15%. This instantly boosts your AOV.
Free Shipping Thresholds
Set a free shipping bar just slightly above your current AOV. If AOV is $45, offer free shipping at $60. Watch how many people add a $15 item to the cart.
