I've used this website many times and it's well worth it.  They offer certificates for participating restaurants around the US (and some great places here in South Florida) and offer them at a discount.  The usual amount is $25 off of your bill and they sell them for only $10.  That's a $15 savings.  They also make GREAT gifts and always run additional discount promotions (right now they are giving away a free $10 certificate with every purchase).  I've used them 3 times for Ft. Lauderdale restaurants and had no issues.  It's also a great idea if you are planning a vacation or a weekend getaway...you can plan ahead and order a few certificates and save some money. 

Once you make your purchase, you print the certificates out on any printer.  It's super easy and I suggest you give them a try.
