You can still buy MyPillow at Amazon, but you’re able to buy cheaper directly from Mike’s site using an online coupon that saved $10 (plus-free shipping). We haven’t purchased yet because I remember seeing his pillows at Sam’s Club recently. I’m going to Sam’s this weekend. Will price them...then buy from whomever is cheaper. I’m a penny-pincher.
A good reason to buy from his website is the selection. When I have seen them at Sam's, they did not have a lot of variety. I do not like a pillow with much loft, so I ordered his flattest pillow from his website and got a "regular" for my wife. Most people like a lot of loft, so the flatter style that I prefer is usually only at the webstore. Just my 2¢.
