Please select AnyGift from the app management in the Shopify admin panel, and choose the products you want to enable for e-gift purchase in the "e-gift setting.”
By default, "All Products" is selected. Note that only products that require shipping are supported.
For the enabled products, the option "Send as an e-gift to someone without a physical address" will be displayed.
Note that the options on the cart page will only be displayed when there are items in the cart.
