If you're already a regular passenger on the Groupon train, you need to check out the copycat sites, though to be fair some have been around longer than Groupon but are not as widely known. It's all the same concept, and each one will give you a different amount for signing up, anywhere from $0-10. Some will randomly put credits in your account, so be sure to check back, and others will send out codes for free credit. You can also purchase these as gifts, and treat someone to a dinner, theater tickets or massage!
Below are the links for all the sites I have registered with and recommend. Please share in the comments, what has been your favorite Groupon purchase?
