HandHeldItems knocks up to 93% off select Apple iPhone 4 cases. Plus, take an extra 20% off via coupon code "20iphonecs". Even better, receive a $1 HHI store credit with your purchase. That's tied with our mention from two weeks ago and puts many items at or near lowest-we've-seen prices. In all, over 1,200 items are discounted (scroll down to see them all). Plus, many items qualify for free shipping. (If not, shipping starts at around $3.) Deal ends December 15.

A best bet is the Silicone Cassette Tape Case for iPhone 4 and 4S (pictured) bundled with a $1 HHI store credit for $2.72 before the above coupon, $2.18 after. With free shipping, that's the lowest total price we could find by a buck.
