There is a new $10 off a $20 purchase coupon for Buca di Beppo! This coupon is for dine-in only, and there is a limit of 1 coupon per visit, per table. The expiration date on this one is December 13th, so you have some time to use it.
In my experience, sometimes Buca di Beppo will allow you to stack other coupons with these $10 off $20 coupons, so if you happen to have one from another source you may want to bring it along with you too. It never hurts to ask!
