Soften the Blow on Higher End Windows

[Frank S.]

Howdy Chitown,

On my rentals I've used $250 windows, they work just fine. White vinyl, they are never used.   Now, I need some higher end windows.  I have installers that can do them for $100 a pop.  Is it worth the time and effort to get windows online, there are a few companies out there, or is there a way to get discounts on Pella or Andersen or similar higher end quality windows?

The windows are 6 feet tall by 46, 32, etc.

Any tips?
