Today only, all customers can get 101 4" x 6" or 4" x 4" Prints, regularly $0.15 each, free when you enter the coupon code 101FREE at checkout at Shutterfly. Shipping adds $7.99 but if you order 99 prints or less, shipping drops to $5.99 which works out to $0.06 per print shipped. This is the lowest price we could find anywhere and ties with the best price we've seen on this size of prints. The 4" x 4" is a new size they added this year, which works great for printing photos from your Instagram account. Sales tax is charged in most states.
