They must have stone tablets with the rules their customer service folks adhere to.
Say you get a 99 dollar mask that is a new style and you get it, you have not idea if it will fit until you open the package.
Well, you just bought a piece of plastic which you can throw in the trash for 99 dollars.
They should have something like 50 percent off another mask at least.
And I am a long time customer. Not anymore.
