Topic: Inaccurate card values
The values for all of the foil full-art lands from Amonkhet and Hour of Devastation are way off. For example, the foil AKH Mountain is $8 on deckbox, but its actual value is just over $5 (http://shop.tcgplayer.com/magic/amonkhet/mountain-full-art-253 ). This makes it difficult to trade for these lands since deckbox only displays the deckbox prices and the trades look far apart in value.
There are other cards this is an issue with too (foil Wastes are in the other direction -- one of them is $2.29 on deckbox while its actual value is $12).
I submitted a support case about this problem almost a month ago, and it still hasn't been fixed. If the site was prompt about making corrections, this would be only a minor issue.
Not only does this make trading on the site more difficult, but this sort of thing is really damaging to deckbox's reputation -- who wants to sign up for a site where the card prices are unpredictably inaccurate?
