There is a nice code that has just come out for $20 off a $20 purchase. It will not cover shipping, but this is still a great way to get a deal on your photo books, cards, calenders, or any other items you have your eye on. Use coupon code TARGETCARDS or PERKHOLIDAY during checkout for your discount.
These codes can be a little funny, so you will want to test them first before you put something together. Put an item in your cart that totals at least $20 and enter your code. If it works then go ahead with your order. Last time they came out with a code like this it was set to work for a couple of weeks and then they pulled it after just one day, so you will want to try and get this one quickly. This code is supposed to work until Dec 10th.
If you are just short of $20, you can always add 1 or 2 photos to help bump your order over.
