The second way, is that they could simply limit a knife to what is called a Ganzaa...typically led by the Busse group. Ganzaaa's typically occur at night, and have specific rules to each Ganzaaa. You have to be online at the time of the Ganzaaa...with an email prepared for what you want to buy. It's kindof a first come first serve type of Hog-fest, so be warned. This is how I got my Wiener...as they were not released in the store. I'm not covering 1/10th of the Ganzaaa details...I'd recommend doing a search on the the word Ganza and you'll find info on the past few.

Hope that helps!
