I just got a large order of small parts from them and immediately made another for some stuff I forgot. The first order was made on a Saturday and I didn't hear anything until Monday. I got an email acknowledgement right after the second order that the package is on the way, should be here tomorrow, so they are definitely still in business.
I bought a few other things from some of the other well-known Norton stockists and a couple of things from private sellers, but I must say Old Britts website and ordering system is just about as simple and convenient as it could be. I certainly hope when Fred and Ella decide to hang it up, someone buys the business and keeps it going.
