If your pillows are bought from a retailer, it will be a lesser product than ordering direct from the factory. Retailers like WM (especially) will set the amount they will pay a manufacturer, take it or leave it.
The manufacturer will take it because WM buys in such large quantities they can't afford to pass it up, therefore, the manufacturer wil reduce the normal fill of the pillow to cut their cost. Much that we purchase from retailers are lesser products, that doesn't mean everything but many thing are.
We have the 'My Piilow', far too expensive to replace yearly, washing is a necessity and they turn out fine. It is always buyer beware especially as seen on TV items, most are junk.
