Sarges,,,Are you serious? If you really don't know that much about credit cards, then I really envy you! Seriously, I wish I could legitimately ask questions like that.
For real, though. When you go to your bank tomorrow to check out the canceled check, then ask them about a credit card. They will probably set you up with a house card that carries like 20 or so percent interest. However, if you pay the balance off at the end of the month, then you will most likely owe no extra fee! If your bank says no, then just pick one of those many thousands that come to you in the mail each month (the ones my shredder hates!) and fill out the app. Most cards you can apply for online, and get an answer pretty quick!

keep us informed on this. This is very interesting. If the check was cashed, you should be able to find out where it was cashed. Then, call that bank (or check cashing service) and find out WHO cashed it. This will probably lead you back to him. Keep the e-mail he sent you. Armed with the e-mail and cancelled check, you should be able to go through the local District attorney and nail the guy. Don't be scared about harassment charges. He's had your money for almost a month now, you have a right to ask for the product! If he indeed cashed your check, the last thing he's gonna do is charge you with harassment. He'll be lucky to stay out of jail. Don't give up!
