Walmart offers the SodaStream Fountain Jet Soda Maker in Black for $39. Opt for in-store pickup to avoid the $5.97 shipping charge. That's $10 under our Black Friday week mention and the lowest total price we could find now by $17. It's also tied as the best we've seen. The set includes the SodaStream soda maker, three 1L bottles, and mini CO2 canister.
