I have forgotten how I found this site:

They are in Florida. I ordered a few things on 2-20 and got notice that they shipped on 3-1, which seems a little less speedy than most these days, but I'm in no hurry. They did communicate promptly that they had received the order and payment, and notified when it was shipped. I'll try to remember to update when it arrives.
