Today only, Groupon offers a $75 Picaboo Credit for $25 or a $100 Picaboo Credit for $35. That's one of the best deals we've seen for Picaboo, which sells personalized photo books. (We saw a $100 credit for $30 in January.) The credit isn't valid on shipping, which starts at $1.99, and it must be used by October 30. Some exclusions apply.
