Dyson deals can be difficult to find. The best times of year to buy a new model Dyson vacuum is during the week of Black Friday: Thanksgiving Thursday through Cyber Monday. Aim for 50% savings. Macy’s, Kohl’s, Best Buy and Home Depot typically have the best deals, but be sure to read the fine print to weed out coupon codes from these stores that exclude Dyson brand. Amazon is also good for Dyson certified refurbished deals. If you’re open to refurbished, shop in May.
