I travel a lot in the military and have a government card that I use for expenses. whenever i get back , as long as it was an authorized expense, its automatically reembersed. but I don't earn anything for spending on a gov't card. Anyone know of any good ideas for cards to get?!? APR shouldn't be a factor because I pay it off immediately but i don't want any montly or annual charges just to have it. some have already recommended Cabellas or Gas cards...any ideas?
