You can use multiple gift cards on a purchase. I meant I wish they would allow you to add $50 a current gift card instead of having to buy another gift card. I'd rather have just one gift card to keep track of than multiple gift cards. i.e. I have a starbucks gift card in my app and whenever anyone gives me a starbucks gift card I can just transfer the $ from the new gift card onto my existing starbucks card instead of keeping up with multiple gift cards.
