I'm sort of new to the site, and I'm not sure if this is the right place to post this or if there is a sticky addressing it, but there seems to be an issue with some value bombed cards with an off-kilter price killing the average. It makes it difficult to use the trade function for its intended purpose. I end up second guessing every price, which doubles the time it takes for me to match value for a trade, especially batches of cheap cards. Wouldn't it make more sense to just pull aggregate data off of something like MTGstocks?

Brings down the average significantly when there are few listings.

Yeah I thought the same when I joined. Basically there are two types of traders, traders that use the average prices on deckbox, and traders that want to use a third party. After a few trades under my belt I decided not to worry too much and just double check other sites to make sure it wasn't insane.
