Good feature!
Glad they added this feature since I'd rather keep a balance and have them deduct my purchases (that are often $.99 or $1.99 each) from it. I used to buy gift cards at the pharmacy, then apply them, but they ran out before I realized the balance was that low. This way, it'll just charge a set amount on my credit card when it drops to the number I've chosen.
