Where to buy electrical supplies in Philly?

[Mike B.]

Hi all Looking for recs on where's the cheapest place to buy electrical supplies (wire, switches, outlets, etc). Fixtures I always find great deals at several stores but I'm taking meat and potatoes here. Electrical panel, breakers etc. Would prefer to go to one store if possible I have my own company so could purchase from a wholesaler if you have any recs. Or are you finding better deals online? Doing a flip and need to purchase electrical materials, hence the question Thanks
