Brick Tattered Woolen Sweater sold at Hustler now for 125 CSC, when the original price is just 100 CSC, let alone sale. It wouldn't make much sense to anyone to pay more for an original less, item you can still buy in cash shop.
i'm pretty sure that item just returned to the cash shop for the sale only, so after the sale is over it will be retired. (i could be wrong though!) the hustler stock is completely random, so it's not on purpose that they listed it now. just random chance. not every deal the hustler has is good!
