Shutterfly takes $20 off orders of $20 or more via coupon code "FIRSTGIFT". Plus, it even stacks with sale items, already marked up to 30% off. That's tied with our July mention as the best dollar-off coupon we've seen from Shutterfly this year. (We saw a coupon for $10 off $10 or more last month.) Shipping starts at 99 cents, or spend $39 or more to bag free shipping via code "SHIP39".
