Yeah, I noticed that when I was working on the forums. At the moment I am trying to complete the list on a text document, but I will keep that in mind when I make the final thread.
At the moment of this post, the most recent item ID is 3798636 which means there are around 3,798,636 items that have at one point existed. As I said before, I don't know scripting, so I am doing this and my list of ToriShop items by hand. It's an alright idea, I have considered it, but I decided not to because it wouldn't be as useful, and it would take an impossibly long time to complete.
Also you would just use it to profit by buying as many of the available, for example, Demon Forces, as possible.
