Thanks to My Good Cents for highlighting the free buffet visit from Old Country Buffet (or Country Buffet, Ryan's, Fire Mountain, or HomeTown Buffet in your area). Sign up for their eClub to get the free buffet, a birthday coupon, and deals throughout the year.
iMommies.com also pointed out an sweet deal: $15 off a purchase at American Eagle (in-store only, not online), good through December 31. There is no minimum purchase stated on the coupon. I love to check their clearance for Bermudas.
Edit: A number of people have been refused use of the coupon, with American Eagle claiming coupon fraud. I don't know all the technicalities, but because I cannot verify the coupon beyond someone's word and want to remain completely above board, I have removed the link.
