I know that's a trifle, but the colors of the price icons seem to be swapped with respect to the site tcgplayer.com.
Example: http://deckbox.org/mtg/Baleful%20Strix, but: http://store.tcgplayer.com/magic/planechase-2012/baleful-strix?partner=DECKBOX2
Maybe it's their fault, because in some sense I feel the color green to be cheaper than red. :)
