What am I missing? Buying from big box stores
I'm a big confused on where to buy federal tax credit eligible replacement windows.
I've pretty much settled on Milgard Tuscany line, and will probably be doing new construction instead of retrofit for the consistent look with my sliding door.
Now, my question is... the quotes I'm getting from a window company is significantly higher than the prices at a big box store, like HD. They seem to be similar in sizes, I'm looking at single-hung, low-e coating, argon filled. Both say it's Milgard Tuscany line. So why is one over $350, and the other $119?
Am I missing something? Both are without installation since I already have a contractor I'm working with.
