If you drink a lot of seltzer water, it is a no brainer to buy a SodaStream machine. Not only do you save the environment with less plastic bottles wasted, you also save a ton of money.
Here is how to get the best deal right now on a SodaStream machine. I would avoid the $125 model they have at Costco. It’s not worth the extra cost especially because it uses the bigger CO2 canister, which you can’t exchange at most places.
Stick with the $80 model sold now at most Staples and Target locations. You get the same functionality AND the ability to exchange the 60L CO2 canisters at Staples and Bed Bath & Beyond locations.
Use the “Where to Buy” function on the SodaStream web-site (Link) to find your local Staples and Target locations that have it and also find which Staples and Bed Bath & Beyond locations do the CO2 exchanges.
Although both Staples and Bed Bath & Beyond do the 60L CO2 exchanges for $15, I would recommend doing the exchanges at Bed Bath & Beyond because you can use the $5 coupon they mail out multiple times a year. Just sign up for the coupon mailing list at the store or on the Bed Bath & Beyond web-site.
For $10 per 60 liter CO2 exchange after the $5 coupon, you get an amazing 16.6c per seltzer liter. You also save the environment with no plastic bottles wasted. If you drink soda, you get the added benefit of better nutrition vs. normal brand-name sodas (Link).
So in summary for the best deal deal buy the $80 SodaStream model at Staples or Target and exchange your 60L CO2 canisters at Bed Bath & Beyond customer service desk for $10 after the $5 coupon.
