I am not sure if it is intentional or not, but in case this is a mistake I am going to post this here.

"The Cash Shop Hustler is very proud to announce he has (somehow) obtained a large quantity of new offerings. For those of you not familiar, he sells a limited stock of one old Cash Shop item at a time several times each day. Thankfully, there's a wonderful board and ping group to help you keep track of when he restocks items. What items are you after that you're hoping to snag from his grubby little hands?"

The shop is NOT restocking a large quantity of items. It in fact has only restocked 3 i believe so far. (don't quote me) The items that are not selling fast/selling out completely are staying in there for upwards of 30 hours. Currently as I am writing this the item "Belt" is in there and it has been in there almost a full day.

Usually when we have these sort of events the stock rotates at least some what quickly, especially when the word "large quantity" of items in used. At this rate it would take months for a "large quantity" of items to be released.

So there doesn't appear to be any bugs with the system. The items will remain until they have been sold out - this is how it has always work, and is intended to be working.
