Groupon offers a $75 Picaboo Credit for $25 or a $100 Picaboo Credit for $35. That's tied with a mention from three weeks ago as one of the best deals we've seen for Picaboo, which sells personalized photo books. (We saw a $100 credit for $30 two days ago, since expired.) The credit isn't valid on shipping, which starts at $1.99. Deal ends May 13 at 3 am ET, and the credit must be used by October 30. Some exclusions apply.
