It looks like Best Buy is clearing some stock and is offering some good deals on wearables lately. First, the Samsung Gear S3 got discounted last week and now Apple's Watch Series 3 with cellular is part of Deals of the Day. The offer is available only for today and it shaves off up to $250 from the price with the most affordable options being $299. The best part is that there's a lot of options to choose from - aluminum, stainless steel and Nike participate and there are more. Source
