ZooGue offers preorders of its ZooGue Social Shell Case for Apple iPhone 5 in 10 colors for $14.99. Coupon code "FreeZooGueAccessory" makes it one cent. With $3.98 for shipping, that's the lowest total price we could find for any iPhone 5 case by a buck. (For further comparison, ZooGue offered iPhone 4S cases for the same price in August.)

Of note, you can buy two of these cases for $29.98 before coupon, two cents after. With $5.97 for shipping, that's $2.99/case and the best per-unit price we've seen.
