Been looking around for some Sharks, and everywhere I look they are either way over msrp or out of stock. Also says they are only released around the holidays. About what time of year are they shipped? Thanksgiving? Xmas? New Years? I'd really love to get ahold of some of these, if I can get them for less than $33/singles or $570/box, that is.

Not looking for sources, just dates. I'm perfectly willing to do my own hunting for the best deal.
