For its newsletter subscribers only, EverydaySource offers a 2-Piece Reusable Screen Protector for Apple iPhone 4 / 4S bundled with a Snap-on Rubber Coated Case in Black for $13.99. Coupon code "S0413MIKR" knocks it to $4.49 and grants free shipping. That's tied with our mention from two weeks ago and a few cents under the lowest total price we could find for these items purchased separately elsewhere. The screen protector comes with two sheets to protect the front and back of an iPhone.
