There is a special offer now through 2/2 (hurry!) if you're in the market for a SodaStream soda machine. Purchase a SodaStream at Amazon and you'll get a $10 promotional credit to spend later. You should receive an email within two days of shipping that confirms your credit, which won't expire until 2/1/2015, so lots of time to use it.
Cheapest model available at $79, also comes in Cherry Red.
