Dooney makes a metro card case that I use it fits my id in a window and my debit card behind and one other card in the slot in the back. I would love to replace it with a different brand but I can't find one. so go take a look and see what you find. they have a plain one in different colors under the search of qt17 and it's only 35.00. I have had mine for about 1.5 years.
if you don't mind carrying a men's wallet. i believe they have what you're looking for exactly. a wallet that opens up, and one side is for the ID, the other side has two or three slots, i forget, for cards and such and they should be under 100$.
I have a plain card case from the outlet that when you open it up has just two clear windows inside...was like $30 I think...usually they have them in lots of colors...
I love the Coach card cases when I want to carry a small bag w/o giving up any of my various cards (credit, insurance, etc) They hold a LOT of cards and still have the nice ID window in the flap for a driver's license or other ID card. They also fit very nicely in many handbag front pockets, such as the Coach Legacy Leather Shoulder Bag, or the Rafe for Target bags.
