Because I was JUST dealing with this problem, this deal caught my eye! For a limited time you can get an iPhone Hard Credit Card Case for only $10 shipped! Then, use coupon code GOLD at checkout to get $2 off your order and get it for only $8 shipped! It holds two credit card sized items, so you can stick your ID and a credit card inside and leave your purse at home! Limit 5 per person.
