I've been spending a lot of time getting Ebay listings up and getting cards listed up on TCGplayer.com.
Tcgplayer is almost impossible to sell cards on without listing your cards for a fraction of what they're really worth but on the other hand when you list on Ebay you're likely facing some of those same challenges in the sense of fees and shipping and just hoping that Ebay draws a larger audience so that you can pull in a little bit more from your cards.
With TCGPlayer it's almost like everything I sell I have to sell at a loss whereas with Ebay at least I have a chance of making a few cents to a dollar on a sale.
I think for the time being I'm going to stick with Ebay. I could try whatnot but I'm not sure if I'm really cut out for the live streaming auctions type of thing. I'll consider it but I'm not sure if I'll make it to that point yet or not.
