Return policy

The local medical supply retailer provided me with bad information. So, the wrong power cord was ordered. Now, I am being assessed a restocking charge, for something out of my control. I don't think that is fair.

Quite easily the best purchase I made all year. The service is outstanding as usual, which is why I continue returning.

Works like a charm.

As promised

Works perfectly (unlike the generic replacement cord I had used for a while) and cpapXchange had the best price.

Great Price, Great Service!

I needed a replacement power supply for my ResMed S9 as the wires shorted out. I was disappointed the replacement wouldn't be covered by my health insurance, and the price I got from my Cpap supply company was twice the price cpapXchange offered. Ordering was easy and shipment was fast. They communicated the order status throughout the process. Thank you!
