Living Social offers a $20 Overstock.com Credit
. That's tied with our March mention as the best sitewide Overstock.com credit deal we've seen. (We saw a $30 credit for $15 in July, although that applied to furniture orders only.) Some exclusions apply, such as books, movies, games, and electronics. Deal ends November 15 at 6:45 pm ET; the credit must be used by February 11.
