Ben and I have been buying these restaurant certificates and giving them as gifts. We just chip in the difference between the certificate and the required minimum purchase. For an average cost to us of $12, we are able to gift a $35 dining-out experience. That's a savings of $23 on our part.
Right now, you can save 80% off Restaurant.com $25 Gift Cert. orders and receive a $15 FTD® Floral Reward. Use code HEART and Pay $2 thru 2/14/10. So, for $2, you get a $25 gift certificate and $15 to spend at FTD. I'd say that's a great deal!
