Thanks @Jonathan Klemm, it's been a few weeks and as sole proprietor/GC, haven't been able to get an account with MSI yet though the intake rep said it would be possible w/o a business. Went in person, was told, "we don't have a price list," but did take down the prices they have stuck on a piece of paper on the bottom of a computer screen, which were different (lower than) from the prices on a written quote from a sheet a floor rep provided. Simply trying to beat big box/Costco pricing and their retail prices aren't less. Was also looking for countertops; the stores near MSI appear to also deal MSI so it's probably just best to go to MSI . . . that is, if they'll give access to corporate pricing.
As for doors, we learned the manufacturers sell to distributors for pre-hung frame manufacture. Can't just call Jeld-Wen or Masonite up. At any rate, turns out our framer uses Menard's doors all the time and was able to install those despite the plans calling for custom-sized doors. For a special outswing patio door, was able to order on a Friday night at Menard's and the door was ready Wednesday.
