Me too!

Even if they were outdated, I still found the prices incredibly useful. They were almost always close enough to give me an idea whether an item was fairly cheap, expensive but buyable, or unbuyable.

And when the price shown was way off (like it used to sell for 50K, and now I can't find it on the shop wiz) that was useful information too. It might be retired and going up, or it might be that someone bought them all up and is running a scam and offering them on expensive trade lots.
