It just doesn't make economical sense trying to carry any quantity of slot cards to the convention let alone the usual lack of interest in cards. I'll be selling my collection direct or via eBay for the foreseeable future unless someone wants to make an offer for everything! Could be a great money making opportunity if you have the time and resources.
Sad that Delcampe had to take the drastic measure to close down most USA accounts and delete all their listings. I had over 50,000 listings with just about everything in my collection listed but they were gone with no warning.
