No hd or the like here until about 6 mos ago. most of the"move in contractors" use them. Other than 12/2 I've not found anything drastically cheaper at hd. Siemens loadcenters,I can get 3.00 cheaper at my supply house, 97.00 for 200a 40sp main breaker,copper buss.Hd store is wrong direction for 90% of my work,can't justify the driving time and effort. Plus I'm a bit of an old fogey, In my growing up years, you did business face to face with people you knew.My supply house still does business this way,even tho they are a chain, Service and accomadation are still king in my book!
