I like this idea. Between Raiden600 and I, we've been compiling a price list, and who sells them where. It's not an expansive list, but, it's a start. I'd love to have this. I've no idea what the coding would be for it though, like, would it automatically be updated when the chests are? Or would the seller have to update it- which is part of the issue as is- some things stopped being restocked due to out of stock or not playing or out of town.
I'd help with this, if it can be figured out how to go about doing it. I'm not much for coding (unless I'm given the idea- I've done a bit with html and whatever the board stuff is before, so I'm quick with coding languages when I want to be), but, could compile the list if need be.
