Most large e-commerce sites including Etsy aren't bakers. They use recommendation engines, personalized site experiences, email marketing campaigns, discount coupons for repeat purchases, dark patterns, offsite re-targeting ads and so on to get you to buy and buy repeatedly.

edit: And the ever fun one of free shipping with a minimum order of X, great way to make you think you're getting a deal by giving them more money.
