"First, vote for the deal that you want. If you vote for the deal that gets the most votes in the end, you will be eligible to receive a claim code only for the winning deal. If you vote for one of the runner-up deals, you will be eligible to receive a claim code only for that deal, at the runner-up discount. (The runner-up discount won't be as ridiculous as the winning discount, but it will still be pretty darn good.) Remember: you are eligible to buy only the deal that you voted for; you need an authorized credit card on your account; the claim codes will be distributed only to randomly selected customers."
It's pretty simple. Vote
for the Zune, hope that it's the winning deal (hey, we have to give Tickle Me Elmo some credit), and if you're lucky enough to score a code, you can pick up a brand new Zune for $90. Unlike the infamous Xbox 360 offer, codes are pre-allocated, so you won't have to worry too much about Amazon's servers dying in the heat of the moment. Voting ends at 11:59pm (PST) on December 10, and on December 12, codes will be randomly distributed. Good luck!
