Pathological liar

Husband and I just bought our first home. All appliances are new, but I wanted a different style fridge. So I suggested selling it on Craig's list. My husband said he'll just call best buy and pretend he lost the reciept and exchange it for the fridge I want and pay the price difference. I was mad that he wanted to even attempt it!
He called and was on the phone with the associate who was trying to find his order for 20min. Of course it wasn't there! We didn't buy it and don't know where it was bought.
It scares me that my husband is so comfortable about lieing. Through out our 10 months of marriage I've heard him stretch truths to make him sound "better". There's lots of examples.
What would you do? I can't picture having children with someone like this. :(
