I think a simple bifold leather wallet is the best. It is impossible to spend a lot on these things which may be the difficulty that many seem to have and I don't care what "name" brand you look for ... they are all pretty inexpensive!! I have 2 or 3 around & cycle them out about as fast as sneakers.
Maybe that is the clue as to when to get a new billfold? When the sneaks are uncomfortable & shabby to be only relagated to just mowing the yard in ... is it time to get a new billfold? A new billfold 2 or 3 times a year is most likely the last thing most guys would do. My current one is at leat 5 years old! LOL Yet, if you are paying for dinner, itn't is nice to pull out a un-worn billfold for the cash or card.
