For in-store pickup only, Best Buy offers the SodaStream Genesis Home Soda Maker Kit in Black, model no. 1017512018, for $49.99. That's tied with our September mention and the lowest non-rebate price we've seen. (It's also a current low by $35.) It includes the machine, a 1-liter carbonating bottle with lid, 60-liter carbonator, and 12-count sodamix flavor sampler.
