Just a dumb question. Why do you use inch mark conduit. As for as pricing if you have a friend that is a electrical contractor, He can get it for upto30% off in some cases. The price you pay at Lowes or Home Depot is about the same as you pay for over the counter prices at the Graybars or City Electrics, CED's etc. Anyone in South Ga., Brunswick, Savannah or surrounding area pm me and I will us our contractors discount and see if it will save you some money.
