How Much Does It Cost to Do a SodaStream Refill Exchange?
As of 2015, empty SodaStream carbonators can be exchanged at participating retail locations for between $14.99 and $29.99. The price varies based on the size of carbonator exchanged.
The SodaStream exchange program allows users to bring their empty carbonators to participating locations and receive full carbonators for the price of the gas only. Some retailers that participate in the exchange program include Target, Wal-Mart, Best Buy and Williams-Sonoma. Most retailers carry only the 60-liter carbonators for exchange. The SodaStream website allows users to search for an exchange location by zip code. Search results include notes about what sizes of carbonators each location accepts.
