I have done these in the past, but never for local to here in Rock Hill...Greenville worked fine and I have heard Charlotte also... but my girl Sharon said this:
Restaurant.com has their certificates for 70% off through Sunday with the code "PUMPKIN". I bought two $25.00 certificates for Firebonz and two $10.00 certificates for Sagebrush and only had to pay $8.40. We do the $5.00 lunches at Sagebrush and Kids Eat Free on Tuesdays at Firebonz so now we can treat grandparents, etc. to a meal by using our certificates.
As always if you find a restaurant you like call before purchasing to be sure they accept them and read the FINE print. You simply print out the certificate after purchasing..so have plenty of ink and if you are doing a gift for someone you may want to print in COLOR with a nice envelope...they never know you spent 70% less!!
