For its newsletter subscribers only, EverydaySource offers this Snap-On Rubber Skin Case for Apple iPhone 4 or 4S in Black bundled with a 2-Piece Front and Rear Reusable Screen Protector Set (pictured) for $13.99. Coupon code "S0507TLCD" drops it to $4.49 and bags free shipping. That's $1 under our mention two weeks ago of this case in a different color and $2 under the lowest total price we could find today for similar items if purchased separately elsewhere. It covers the back and sides of the phone. Coupon ends after 1,000 uses.

Of note, the case is also available in White with the same screen protectors for $4.99 with free shipping via coupon code "S0506NCXH". That's still a price low by $1.
