The concept behind Customer Vote is pretty cool actually. They put up three items and show you what the price will be for the special and how many of them will be available. You then vote for which one of the specials you would most like to take advantage of. On the designated day (there are 6 rounds) for each round, all the members who voted for the winning special get thrown into a random drawing and some of them (up to the amount of items) get an email that allows them to take advantage of the special.
Even if your special doesn’t win, you might still get a chance at the item at a slightly less spectacular special, so it does make some sense to vote for what you really want rather than the current winner. The first round ends on the 27th of November 2008 and the last round ends on the 3rd of December so you’ve got a few days to get your votes in.
