Check Craigslist help please?!!?

Highly likely that the check will bounce back a week after you cash it.
Actually, I'll go further: he'll tell you he made a mistake with the check and ask you to wire him the remaining $2000 back and keep $50 for your trouble.
So he's expecting you to deposit it, the check gets initially deposited on your account, pending final validation, you use that money to pay him back, then the check gets bounced: you're $2000 out of your money AND have to pay for the bouncing fees.

You want my recommendation? DO NOT cash it/deposit it. Tell him you deposited it, thank him for the extra tip in the check, and ask him where he wants you to send the styler, if he tells you to send the rest of the money back at him, contact your closest FBI and/or police office without delay. I hope you kept the envelope the check came in.
