I as well as other players have had problems with the tank shop, my proffered method of paying would be a visa gift card i had a $100 dollar card and i was going to use it for tank but when i tried to use it didn't go through i emailed tank and they just told me that tank doesn't exert visa gift cards and i don't have a credit card i would use paygarden but i have heard some things about having big problems with them so i would really love to be able to use a visa gift card so tank if you would like more people to buy please consider making this an option.
