Does CartThrob allow multiple carts? Is it possible to have 2 unique carts? 1 is a standard cart. 1 is a custom gift box cart — customers will fill up this cart with products that they are sending as a custom gift boxes to someone. We don't want to use 1 cart because then we have to deal with multiple shipping addresses and we want these custom gift box orders to be made up of individual product SKUs from our product catalog. LemonStand uses cart_name for cart assignment.
