This seems to be account specific and may not work for all but, it seems to work on old and new accounts. If the code doesn't work on one account, try entering it in one of your "friends" accounts. Anyway, enter FIFTEENOFF in the special offers field to get a $15 credit for any purchase over 15.00. Supposedly this is valid for 6 days after entering into your account, but offer expires TODAY and must be entered in your account NOW. It will show an expiration of sometime in 2109 (over a hundred years from now) so obviously its a typo. The real expiration date was reported on slickdeals.net.
I'm not sure if you can combine with the previous offer mentioned HERE where you can get $10 credit. But I'm thinking it may combine since the $10 credit is a unique code, and the other is a targeted offer. Try it. I can't because Shutterfly.com is blocked at work - but I'll do it later.
