Tell him he will have to wait to come over when your husband is home, and that you want to go thru the bag before you refund his money.
The only thing I have ever bought from Craigslist was my daybed, and pretty much had to meet them at their house, lol. We went to look at it, and the mattresses it came with, left half as a deposit, got a receipt for that, and then came back with a truck on the weekend. THey helped us to load it, and then...came out and gave us two sets of sheets and a comforter that had not even been included in the ad....so I did good. But I am really leary of CL offers. Be careful.
