I support option #1
We would be eligible for 60 blue wave packs (18 packs per box * 12 boxes per case * 10 cases = 2160 packs / 36 packs per redemption), which would require you to send out 12 separate mailings, each containing 180 wrappers.
My question is, what happens after we redeem them? How do they get split? There will be a total of 60 packs and 300 cards (if we get all successfully redeemed). Does each recipient resend the packs to you once we get them and a new break done with these packs in the form of a hit draft?
