What I'm trying to say is what sets you guys apart, or why would I as a seller (or buyer) prefer to use Mana Pool over TCG?
Is it commission? I'll say from personal experience that 10% commission (or 10.25% or whatever) is quite expensive as a seller. If the commission is the killer, are you hoping to capture more of the market from TCG for Magic? Is it sustainable to run a price war on commission?
Genuinely asking all of this btw, I do prefer the design here to tcg
2) TCGPlayer is the market price, and it's a nicely liquid market. And their owner eBay is worth $25B. And there is stiff competition from whatnot.com and goat.com in collectibles. It is an incredibly hard and fun world to build in. I think e-commerce is going to continue to evolve, and Amazon or whatever isn't the end state.
