Don't shop here! I went to this store when the power cord on my cpap started sparking. I told them there was a recall on the machine, and I had been advised to take it to a store for replacement. Cpap direct sold me a new cord (they gave me a discount), so they didn't have to do the paperwork. The machine CAUGHT ON FIRE that night!!!!! They should have checked the recall details, they needed to send the machine back for a replacement!!
