Just got the October Coupon Book for Costco. They have $40 off the Winix C535 Air cleaner with hepa filter starting September 28, regularly $139.99. This is basically a rebadged 5300-2 that comes with two years of filters and a remote. In store or online.
Thanks Equipto: " To make it an even better deal, buy it from https://express.google.com/produc...64_9090995
and use code NEW20 [or FIRSTORDER20] to reduce it to 79.99. My total became 91.54 (CA tax included) shipped. Must be a first time shopper though."
