A:Answer Prospective Dyson Owners: These warranties once stacked, but longer do. I read through the various editions of the terms and conditions and this was removed from the T&Cs in Oct 2019.
I purchased a Dyson yesterday from Best Buy and was told by multiple employees in the store the Best Buy warranty begins after the Dyson warranty is over. I was very excited about combining the 5 year Dyson coverage with the 3 or 5 Best Buy Geek Squad Protection (GSP). However, when I received the full details of my warranty in my email today, it very clearly stated that the GSP expired 5 years from the date of purchase. Alarmed, I contacted Best Buy customer service immediately and was told these warranties no longer stack. I went back to the store, spoke to higher-level employees, and they confirmed this. I'm sure the vacuum is great. But, THE reason I purchased from Best Buy was the stacking coverage.
