Most of us here do not buy large quantites of AFCIs at any one time. I think the most I have ever purchased is 10. For those of you buying larger quantites, is the price that much different? Can it get down to the $15 difference that is talked about in the NEMA article? That reference is dated to 2003.
Yes, my thoughts also, $15 each? Not in the real world that is. Everyone will zero in on that as bogus and then disqualify the entire paper because of it. Lies have a tendency to cause you to question everything. When you consider the purpose of the paper why did they have to bring price into it? It was a good paper by itself.
You would be lucky to find someone bowing them out for $15ea on Ebay.
