Respshop--any comments?

Has anyone used RespShop for CPAP/APAP machines, masks, supplies, etc? They offered me a really good deal today with a free either Comfort Gel Nasal mask by respironics or a Devilbiss Flexform nasal mask. They did this to price match what other sites have reduced their Devilbiss Intellipap Autos to right now.
I would appreciate any feedback.
