I tried using Albion2d for commerce but it was completely inaccurate. Due to this I find it a little hard to believe other info off Albion2d such as the meta data.But i bet you can get same info from:
It goes by the last sale, accuracy is actually pretty good. However if something sold to an order instead of a buy than it can skew prices a little bit. Still gives you a pretty good ball park of where the item stands. I'd love to have an auction program to best.pin point profits. However I think this is basically a shot in the foot because it is the fun of it. Some items have insane swing, but I prefer liquidity.
