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 as 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 Music Life Graphic Case for Apple iPhone 4 or 4S (pictured) with a $1 HHI credit for $4.13 before coupon, and $3.31 after. With free shipping, that’s $2 under the lowest total price we could find for a similar case elsewhere. It features pre-cut openings that allow full access to the iPhone 4′s functions.
