I'm not sure if it's possible but it would be awesome if we could fetch prices from different traders?
Because the prices the app shows me are often different from the german traders. That's why I would love to choose a german trader like "miraclegames.de" or "magickartenmarkt.de", even ebay.de would make the deal.
Any chances this will ever happen?
Yes, email them and complain. As soon as they want and have infrastructure, I shall add them.
Which infrastructure is needed?
They should be able to offer their prices online in some sort of reasonable format.
