MM Coronavirus Update

We’re changing our phone hours to 9:00 AM to 3:00 PM Pacific Time (Monday-Friday, excluding holidays) so we have more time to process orders and get them out to you.

Please be aware
Our supply chain is suffering major pandemic-related disruptions. Many of our suppliers shut down for a time, and like us are operating with reduced manpower. Meanwhile, demand for MM products has skyrocketed. Thank you! We’re a small company and we regret our website isn’t fancy enough to inform you of back orders when you buy something. Please understand that we’re working as fast as we can to fill your orders.

UPS Shipping Times As of March 24, UPS no longer guarantees the shipping time for any shipment. i.e., expect shipping time to lengthen.
