Limited for 'purchases'
I found out when I had a large balance on my gift card that none of it can be used to renew a Prime membership. To me, that's one of the most important and convenient ways to make sure your stashed away funds are used on what the site wants you to use them for. If people don't like or don't have debit or credit cards for whatever reason, using a gift card balance should be acceptable to pay for Prime just like a debit card would be. If the balance is there, the balance is there. If not, don't let the transaction go through. Simple and convenient. Other than that, I like having a little extra on a gift card in case I want to purchase when I don't have the card I want to use on me at the time.
