These 0.4mm Ultra Thin Bendable Snap-on Back Covers for iPhone 5 drop to $3.99 at Newegg. With free shipping, that's the best price we've seen on any cover since the iPhone 5's release (and a significant discount from the $25 list price). These are available in 6 color options. There is no sales tax (except CA, NJ, and TN).
