I emailed and Eric, Assistant Marketing Director, replied that they still had WMs in stock. Apparently they'd pulled them from the web site... maybe under pressure from WM headquarters also in San Jose?
My friend was interested in buying a Mitylite but didn't make the 9/1 deadline. Yesterday Eric replied with an offer to match the 20% and also include the no sales tax promotion inside CA for him. And they have free shipping. That made it a great deal.
Feel free to contact them. You never know!
