Hey listen-- Restaurant.com KEEPS 100% OF THE REVENUE and most of the time features businesses with out their permission. Restaurant.com thinks these businesses should be happy they are sending people in (and keeping 100% revenue) but people who use these coupons are cheap and only want to spend what the "certificates" state it's for, in other words, if you buy a $25 gift certificate for $5, people don't want to go over the $25
When business owners called up to get their name taken off websites, they would say it would take 90 days and that is a crock of you know what. It takes seconds to remove them. Bottom line, don't be greedy, think about it. $5 for a $25 (especially when you're not willing to spend past the $25) you get what you pay for.
