There are 3 types of prefilled carts:
- v1: Link to checkout page and can't edit cart. Eg. https://go.tabarn.app/r/yQYm
- v2: Link to checkout page and allow to go back to edit cart. Eg. https://go.tabarn.app/r/GmoK
- 🔥 v3 *NEW*: Link to cart page and allow to edit cart. Eg. https://go.tabarn.app/r/idmz
Example of v2: a BOGO offer, buy one get one free. Both products pre-fill the cart and the discount is automatically applied.
