We are not ones for preaching; however, we would love if you brought your empty disposables back to our stores so that we can dispose of them properly. Any customer who brings in empty disposables will get 10% off their purchase of a refillable salt device and salt juice bottle. On average, that's about $5 dollars off the initial investment, and you'll save hundreds in the long run. (Caliburn, AVP, Nord, zero, 100+ salt flavors, etc)
