KOT our suppliers are providing prices for 2-3 days only on any wire. The price of copper has increased 6 times since Jan 1st and there is supposed to be another increase April 1 (not a joke, coming from multiple suppliers). If I were your boss I would be quickly placing orders in the next day to ensure you are getting wire for what you are paying for it now.

As for supply on other items, we have seen supply issues with breakers. Most breakers are manufactured in France and with COVID shut down last year it really hit the stock levels. We are still having issues finding odd sized breakers but for most 15A & 20A they have caught back up and are fairly available again. PVC pipe and boxes, haven't had any issues, although all our pipe and boxes are mfg'd in Canada and since these factories supply construction have been deemed essential so were never shut down.
