I recentley read of the House of Blues deal thru Restraunt dot com. and Discover cash back. So I go to Discover Card Cash back (20% cash back) then to rest dot com, use the promo code MAY for 80% off. A $25.00 gift cert requires one to purchase $35.00 worth of food. We are a family of 4, so I buy 3 $25.00 gift cards for House of Blues for $10.00 each, with a discount of $80%, pay with Discover to get @20% cashback. When I print out my receipt/gift cert, it notes "one may be redeemed, per party, per month". So my extra two are no good to me! If I knew that prior I would have purchased a $50.00 card. Has anyone ever used or do they allow more than one cert?
