Cyrus: Can you count, suckers? I say, you'd never use eBay... if you can count!
I have stopped selling prewar baseball cards on eBay for a reason that I've said before but is on point so I will repeat it: math. An occasional seller like me spends 10% on Final Value Fees, 3% on Paypal fees (including charges on shipping), has to go through the hassles of listing and fulfilling orders, and has to risk the uniquely eBay style punitive refund and return rules, nonpaying bidders, etc. Or I can consign prewar baseball cards to any number of AHs for no commission and vig of anywhere from 12%-20%. Am I really going to waste my time with eBay and deal with its hassles over a lousy couple of points on a $1-$100 card?
I've been very pleased with my results off eBay for prewar baseball cards. The smaller AHs have good client bases and offer value for the service. I think more and more sellers are discovering that there are alternatives to eBay that make sense in the context of time and effort and risk...if you can count.
