I'm reposting this to add a few deals expiring this week.
Now that Halloween is over, Snapfish is offering free shipping on 50 prints (4"x6"). I'm sending some photos to the great-grandparents with this one. Use the code BOOPRINTS by November 8th and get free standard shipping from Snapfish.
NEW: Buy one, get one free 8" x 11" photo book by mail from Snapfish. Put 2 photo books in the cart (they can be different content, but free book includes same number of pages or you'll pay for the additional ones) and you'll get one of those two books for free. Use code FALLBOOKS09 by November 6th. You can't use any additional discount offers with this one, and you'll pay taxes/shipping etc.
Also new: free shipping on 40+ photo cards at Snapfish. Use code EXPRESS9 when ordering 2+ sets of cards by 11/30/09.
Shutterfly has a deal through November 4th - up to 50% off and free shipping for orders over $30. The code is SHIP30.
At Shutterfly, photo books are 10-50% off depending on the size. Get 3 free custom greeting cards using the code 3FREECARDS by November 4th. I already got mine -they look great, and cost about a dollar in shipping/tax total.
