Le site cpap.com est-il sûr ?

Beware - Saw something stating FREE GROUND SHIPPING, and upon entering my address, I was offered GROUND for $7... So I put in all the information and got to the final confirmation, where basically if I had clicked the button, I would now be charged full price + 7 shipping, and have the mask sent to me.. Instead I closed the page, only to see a pop-up window saying Good news! Turns out you qualify for FREE GROUND SHIPPING! So wait, hold on a minute.. I almost just got suckered into paying $7 for shipping? And now you offer me free shipping because I didn't seem interested in the price you offered??? Reminds me of a kiosk at the mall. Completely unacceptable. I don't care if their masks are a dollar, you won't see me on cpap.com again after a switch like that. It really proves they are out for money, and they won't give you a deal unless they have to. I wonder how many suckers they conned into paying extra for shipping. Didn't realize closing my browser window was the equivalent of walking away from the perfume salesman at the mall. Oh wait! Please don't go! We'll lower the price for you! Pathetic.
