For new customers, Shutterfly takes $10 off orders of $20 or more via coupon code "CANDY". That's the best dollar-off coupon we've seen from Shutterfly since we saw $15 off orders of $15 or more two weeks ago. Shipping starts at $5.99. Deal ends October 31.
Alternatively, coupon code "SHIP30" bags free shipping on orders of $30 or more and may yield greater discounts than the above coupon. (These coupons do not stack.)
