ShowClix – Cashback, Rebates & Rewards

I've been buying tickets from Showclix for a few years. They seem trustworthy, especially since a lot of the conventions and concerts I attend use them. The only issue I have with the site is they don't accept my current phone number. Mind you, a few years ago my state has had to update the area code due to running out of phone numbers. It seems many websites and card readers haven't recieved the memo, so my phone number along many other peoples' phone numbers show up as an invalid phone number. This is annoying since I don't always have access to a printer. Other than that minor issue, the site useful.
