Mountain Dew / Doritos promotion has PAX East and Prime (2014) 3-day passes available
If you happen to have 25,000 points saved up for the "Every 2 Minutes
" promotion from Mountain Dew and Doritos (the one where you can bid in auctions for Xbox One), you can spend those points in the marketplace on that site to purchase a 3 day pass to either PAX East or PAX prime. As of right now it looks like they have 40 East passes and 39 Prime passes available. It seems that there is a limit of one of these items per person. (The items are arranged in "tiers" and you are limited to one "tier 1" item per person, so it's not one of each, per person, it's one total.)
I've already got my passes for East, but I hope this info helps someone! Also, I'm totally not affiliated with this promotion or any of the companies involved in it. I just wanted to share the news in case it might be helpful.
