$2 for iPhone 4/4S Mesh Ventilated Hard Case + Screen Protector
I found this great deal on iPhone 4/4S cases from Case Station but you need to be a member of their Facebook fanpage to take advantage of the deal. All purchases are made in the Case Station website but you need to indicate your Facebook username so they can confirm if you liked their page. Hard cases come in black, white, pink, orange, red, blue, green, light blue, purple, and yellow. There are 100 pieces of each color but you can't choose which one you want. This will be great to have lying around the house and ready for when you need a quick gift for someone. $20 for 10 different colors is not a bad deal. It comes with a screen protector and microfibre cloth so you won't need to worry about maintenance and cleaning.
