Suggestion: Prices and Vacation Mode

So today I noticed that the "lowest Deckbox price" for Eidolon of the Great Revel was at $1.47. Which is pretty low. So I click on the link to see who's selling it, and... the user is on vacation.

Obviously this seems like a problem. I could screw with a lot of Deckbox prices by listing cards at $0.01 and then setting my account to vacation mode. Obviously I don't think this guy was doing this on purpose, but it means that there's significant deviations between the quoted price and the actual price you can buy cards at when the low users are on vacation, and that's probably bad.
