Hello. I am new to his group. I downloaded this app because I am looking for an acceptable way to sell 2 pumps that my kids are not using anymore. We originally bought them for my 13 and 9 year old, but ended up going back to shots. They are both the same pump, a t-slim G4. One is used, the other brand new, unopened and still in the original delivery box. If there is any interest here, please let me know. If this app is designed for a different purpose, I apologize. Thank you!
