Does anyone have a working Dexcom transmitter theyd be willing to part with?

Anyone have a working Dexcom transmitter that they have replaced and would be willing to mail to a mom of a two year old boy that has lost his transmitter and has 6 weeks left to go to get a new one via health insurance?  Dexcom told her $250 to replace it but they don't have the funds at this time.  If you have one you would be willing to send please leave me a comment, or send me a message via my blog or contact me on facebook.  Thanks!
