Arrgh, this is a frustrating thing.
Only 100 items listed, no sorting, hard to find items you want for a good price (it's an unsorted mess currently).
No cost to list items (I've only done ingredients so far). No time limit (that I've seen so far).
PS. No Bid/Buyout options.
PSS. Here for the forum Suggestion link I made, if you like what I want added, please add to the suggestion. The more visible it is the better.
