Amazon offers the SodaStream Source Sparkling Water Maker Starter Kit for $82.99. Clip the $15 off coupon to cut that to $67.99. With free shipping, that's a buck under our mention from two weeks ago and the lowest price we could find by $15. It includes the maker itself, a 1-liter carbonating bottle, mini CO2 carbonator, and a rebate for a 60-liter carbonator.
