From their Facebook page:
"If you are trying to go to our website and cannot, it is because our server is down. We urge you to call the store directly @ (586) 296-6116. We apologize for any inconvenience ! Please ask for Pat or Andy to place an order, we will be more than happy to assist you. Thankyou"
I just did some IP Pings and it looks like their hosting company is either down or out of business. In that case, they have to find a new host, transfer domains, and possibly redo the files that run the point of sale, etc... Not a minor undertaking.
