Sure will. Just bought 1 $50 physical gc in the app. If it works as expected I've got plenty of time to do the rest.

My next question would be if I can just buy $150 at once or it must be $50 increments. The terms say you can spend $50 in one or more purchases so that means it can be cumulative until you hit $50 to get the $10 credit but I wonder if one spends $100or $150 at once if you'll get 2 or 3 times the $10 credit as well.
