Figured I'll share this one.... My dear sister just picked up for me a SodaStream 60-Liter Carbonator at Kohl's which is now on sale for $14.99 (29.99 @ Staples)! Most (I think) Kohl's card members received a 30% off in the mail these days (Coupon code FLOWERS30) which brought down the price to 10.49!! (They didn't know how long sale price will last) Good luck! Enjoy!!
EDIT: Wasn't an exchange, was a spare bottle
