After applying gift cards to an account, Amazon.com customers can check card balances by selecting the View Gift Card Balance link on the Your Account menu, according to Amazon. Amazon automatically applies any remaining balances to member accounts when shoppers use new gift cards to complete purchases.
Shoppers can also add funds to their active cards electronically by using the Reload Your Balance feature, which is accessible on the Your Account page, notes Amazon. For ease of ordering, Amazon processes the reload balance as a gift card purchase and applies it to the member's account upon approval. Members can also choose the automatic reload feature to keep a gift card balance from dropping below a preset amount.
