I'd vote for handling it like Houdini's breaks
... Do a random and the top 12 get 144 wrappers (4 redemption packs each). Those winners send an extra $10 to the host for shipping and his trouble. The wrappers of course would need to be shipped out the day after the break since the redemption is limited.
We would be eligible for 48 blue wave packs (18 packs per box * 12 boxes per case * 8 cases = 1728 wrappers / 36 wrappers per redemption). Each household is allowed to redeem up to 5 packs, but if we do 4 per winner, it will divide evenly.
Vince if you would be up to that, let us know and if anyone else has a different suggestion or supports this, please speak up.
