HandHeldItems takes an extra 20% off iPhone 4 and 4S cases via coupon code "20iphonecs". With prices starting at $1.59 after coupon, that's tied with our mention from last week and the best discount we've seen on these items from HandHeldItems in recent months. Shipping starts at $2.85, although many items receive free shipping.

A best bet is the HHI TPU Edgebandz Skin Case for Apple iPhone 4 or 4S in Black (pictured) with a $1 HandHeldItems credit for $2.72 before the above coupon, $2.18 after. With free shipping, that's the lowest total price we could find for a comparable case in any color by $2.
