Two of the nationwide Groupons today would be great for holiday gifts:
Wilmington-Newark (check on sidebar): $60 for up to 11 letters on a personalized sign from Hal Jaffe. I absolutely LOVE these signs- you can take a friend’s name and they put it together to make a really cool sign. Would be a great gift for someone just moving into a house! Shipping is included.
San Francisco (check on sidebar): $35 for $70 Worth of Merchandise from Marbles: The Brain Store. I have several friends who love brain teasers!
