Having watched their sales regularly (on the US website) and just double checked my email, I'd note the following promotions that you can interpret how you wish, but seems to be at least 30% as a standard expectation, who knows with COVID what that could mean this year:
- 30% off, approximately every 6 months in recent years
- Fixed 1500USD off beds - every 2 months, recently
- Smaller amounts: 20-25%, free shipping, regularly
- Christmas 2019: 30% off / USD750 discount on bed
- Christmas 2018: 30% off
- Christmas 2017: 35% off
- Christmas 2016: 35% off
Depending on status, you can guarantee a 40% discount on your
50 nights benefit (noting you may have just got promotion nights towards this in the past day or two):
Save 40% on a bed from your favorite hotel brand.
