If you can keep up with it easily then I'd offer it up on sites and facial book. Maybe have them type in a code just to make them work a little.

You should have the sale and then introduce some of the new hotness
AFTER. Move a little bit of older inventory and then bring the noise with some new stuff. If you had Soundwave after that and if you can do up the Shockwave barrel at all I think you'll do well. Those two items could be well received. At the end of the day while it is good to hook the community up it's still about the dollar dollar bill y'all.
