I like the idea of pulling some of the cheapest items from the pool as well. I didn't know Amber and Ariel would remove the least valuable items from the bottom of the list each time they update it, and I think expanding on this idea a bit could be really good. I seem to recall hearing the Keith had set a cash shop vending machine to only vend items that are worth at least a certain amount of sP (I think it's the SubQ/costume trunk one). Is it possible to do that with The Hustler as well to take some of the load off of Amber and Ariel by automating the process?

I agree on not upping the restocks to be unlimited. That idea could have too many negative economic implications should someone go in and buy up tons of a specific item. If there's a demand for it perhaps the limits could be increased, but unless this idea would definitely yield extra profit for the site I think the user risks outweigh the potential benefits.

The cool down idea is one I really like though, and since it's currently being implemented with the NPC shops maybe there's functionality to include this with The Hustler as well? I seem to recall when the was popping up at least once a week for what seemed like at least a few months in a row, and it finally had to be removed from the queue altogether. There were so many missed opportunities for other items to come available during all the times that one item kept appearing, so I think this would definitely be a benefit to users looking to buy more items from The Hustler.

I definitely agree with this. A once-a-day restock if the item hasn't sold out by the end of the 24 hours sounds great! It's always sad to see the same crummy items languishing there, instead of something I could purchase with my money.
