Honestly, I don't think it's that big of a deal. I have bought and sold high dollar items on eBay, and this experience is not unusual. Payment in 24 hrs? Give me a break! That is quite unreasonable. People have got lives; not everyone can sit by eBay all day and watch the minutes tick off of the clock. My advice to you is RELAX! A week is not an eternity. Give the guy a break; he has already offered to pay you the fees.
