"7 days passed and I hadn't heard back from josh. In my mind, if I were so interested in buying something for resale, I would go out of my way to complete the purchase. When I didn't hear back from josh after 9 days, I assumed he was not longer interested and I listed them on ebay to make a profit, just like anyone else would."

Bam,
The day after we did not meet in line I told you I wanted the chips and would get them later.

Ten days later I asked you when I could get the chips. Your response was that I waited to long. IS 10 DAYS TO LONG???

The right thing for you to do would have been to send me an email asking if I was still interested before you put them on eBay.

What it comes down to is that I offered you $37.50 for the Billy Joel chip. You accepted the offer. A few days later you sold one on eBay for $65.00. Seeing you could make more on eBay you did not want to sell to me at a lower price.

You be the judge on this. Who is wrong here?
