Now until November 10, 2012, you can purchase Gold Points and you will get a 50% bonus. You can buy in increments of 1,000 points for $7 + the 50% bonus. So you could get 15,000 points for $70 (10,000 purchase +5,000 bonus). There are some hotels that you can get a free night for 15,000 that are more than the $70 so this would be a great deal! Or if you need to top off your account this will be a good way too.
Also there is another BOGO promotion where if you stay one night at a Radisson you get a free night certificate valid until Dec 31, 2013. Check out the post by New Girl in the Air!
