I noticed that the price on the foil Jace AoT and Vraska promos from the new duel decks is zero. The TCGPlayer pages for these cards works fine (eg. http://store.tcgplayer.com/magic/duel-decks-jace-vs-vraska/jace-architect-of-thought), so what gives?

Its not zero
I have jace in my tradelist set as foil jvv and shows 9.99 same with remand and vraska when i had those aswell

You have your JvV Jace marked as promo not foil. Fix that and his price will display correctly.

Okay, you're right, thanks.

Although I did have it as promo only because the non-foil/non-promo price also shows up at 0. I had not tried choosing the foil toggle.

Which honestly I don't think should be necessary anyways, given that there's no non-foil version of the card. But I won't complain since I can get it to work.

You have to do it however tcgplayer does it basically. It is their data, so if they put the price for JvV Jace as foil, you have to mark it as foil. Deckbox shows 0 for the low/mid/high for non-foil because there is no value returned for a non-foil JvV Jace.

There's no reason why there couldn't be a rule stating that if a card only has a valid foil price, then inventory without the foil toggle will just use the foil price.
