On ebay I have a "no returns" status- but in reality I take returns if somebody asks for one. I have a 100% rating (I'm not a big seller).
This keeps out the Riff-raff, I think. Sure, some people who might buy - won't - simply because I have a no returns policy. But I have a bunch of repeat buyers and I know the people who do buy, intend to keep the item unless it really doesn't work.
With the Tradesy model, that hesitation to return on the part of the buyer isn't there. I've had one buyer on Tradesy buy 3 things from me, in different transactions, within a month- and return them all.
Even
Nordstrom is starting to ban serial returners so I know this issue of returns is a pain point for every seller big and small. I think Tradesy is going to need to address it.
People who sell pre-loved are probably more ok with the Tradesy model vs those who sell new with tags.
