They have a new game to win instant discounts on hotels or at their online shopping club. Discounts are good for a month, and the hotel discount has a 2-night minimum stay, so not all that great. You are also entered into their Las Vegas sweepstakes.
You can use multiple email addresses to play multiple times, at your own risk. The shopping club requires registration.
Edited to add: It appears you'll instant-win either a 10% hotel discount or a 20 chf discount at their store, so it's really not all that interesting. Bring back the roulette wheel.
