I'm a deal-tracking pro — today's best sales are on Roku, Ugg, Patagonia and Shark

Shopping is my favorite hobby. But it's also my job! I track deals by researching price histories and browsing through sales to find only the best of the best. And today, I'm listing the 10 best sales you can score on the web. First up, nab a 55-inch Roku Smart TV for over 30% off (and save yourself a whopping 300 bucks!). You can also get 40% off a pair of Ugg snow boots, a lightweight, yet warm Patagonia jacket, and a handy Shark vacuum-mop combo. Keep scrolling to check out these deals and more before the day's end.
