I support the removal of "auto-accept" as well.
While I have not yet bought, sold, or traded on Deckbox, I might choose to someday, and I think both sides of any exchange agreement deserve protection.
To all the people saying "sellers need to be more responsible" - some of us who sell/look to sell are just ordinary people with a huge inventory and very little time. It's why I would consider selling/trading here - the time efficiency in being able to *find* deals is strictly superior, especially given the current global pandemic issues, and I have a lot of cards I can move. However, I feel as if I, as a seller, don't deserve to get screwed because a price spiked and I didn't have a chance to reset my prices because I was at work or otherwise occupied at the instant of the spike. Please remember that there are tens of thousands of unique cards and probably over one hundred thousand unique printings of cards, and that's a lot for someone for whom selling is at most a side gig to keep up with on an instantaneous basis.
Would there be a way (and maybe there is and I haven't seen it yet) for sellers to set prices as some sort of percentage of an established price (like when we have TCGPlayer prices up here)? If I agree to sell all my cards at, say, 95% of TCG Mid, then my prices would just update automatically as prices spike... would it not? I feel like that could solve a lot of problems. Of course, I have no idea how feasible this kind of idea is, as I haven't done coding in so long that I can safely say I don't code at all. LOL
