Pretty sure the demand for NS stickers is too high right now so they had to get rid of the big dick package. The NS sticker master Jason has been pumping out stickers like a fiend. I'm sure you could send him a message or he will post in here to provide a better explanation.
Yeah unfortunately I've been super busy with the store (about 50 orders a week, keep em coming guys!) along with ordering new product (new t-shirts, stickers and a few random things) and working for IF3.
So expect the big dick packs sometime late september
