LivingSocial has a deal going on right now. For $10, you get a 20 page, hardcover photo book from Picaboo. I've never used Picaboo before, but the designs look promising. I just purchased this deal and plan on using it for the travel photos I'll have from our upcoming trip to Scotland (remember when we won airfare?).
You can find the $10 deal here. I think a photo book would be a great (and now affordable!) gift idea for grandparents. You can also use it to create a book for your kids (you can see what I made for Oliver on Shutterfly here for ideas). Enjoy!
