PC Micro Store offers the Young Micro TPU Crystal Skin Circle Design Case for AT&T Apple iPhone 4 in Clear (pictured), Smoke, Blue, Green, Red, or Purple for $6.95. Coupon code "IP4GSCRCIR" drops it to $2.50. With free shipping, that's a buck under our mention from last week of a similar TPU crystal case for the iPhone 4 (although that deal included a screen protector and cleaning cloth). It's also a $5 drop and the lowest total price we could find for this case. It protects your iPhone from scratches, dust, and more. Coupon expires after 1,000 uses.
