I hate selling and buying anymore..

I was dealing with a guy the other day that had a car part listed for 10 dollars, but when you read the add it said "make offer". I PM'd him and said "I can be there in an hour with the 10 bucks". He said, "do you know what they cost new?" I said "yep, but your add says 10 bucks". He said "read further, make offer". I simply said "i cannot buy it and sell it to me too! Would you load a shopping cart up at walmart if no prices were present??" He reluctantly gave me a price which was higher than I would pay, end of story.
