Best place to buy rigid foam insulation?

In general, where have you found the best price on XPS and Polyiso? Lumber yard? Big box stores? Other? We are in the design stage of a new custom home project and I want to analyze price/performance as we are creating the plans. In the past I have relied on my stucco sub to provide it in his bid, but we will install on this project. Thanks for your input!

I have found the best prices going directly to the manufacturers. And have found better deals on EPS than XPS, not to mention the less-nasty blowing agents.

Large commercial roofing suppliers have it this way. Also if you are buying large quantities annually you can work out quantity pricing in my area with our better lumber yards.

I looked all over for a source of reclaimed rigid insulation and ended up finding a supplier locally - on a buy and sell website.
It was in very good shape except for a few dings and holes from fasteners.
I bought a pile of 4" xps for my foundation for a little more than half the best price I was quoted for new material.

If your area is like my area, you've got at least one really weird lumberyard. We got our polyiso at pretty good prices there. Check craigslist too, of course.

Thanks for all ideas. I like the idea of using recycled/reclaimed.

As a follow up, I found reclaimed 3" polyiso locally for $15 per 4'x8' sheet.

I can vouch for Green Insulation group. Price was good and the reclaimed 4" xps was in fine shape, almost like new, but a little dusty.

EPS is going to be less expensive than XPS and you can buy it with 10% to 15% recycled content. Universal Foam Products is a great source http://www.univfoam.com. ABC Supply probably sells more polyisocyanurate (most used for commercial roofing) than any company in the country. Either of the two companies can help with XPS.

I know this is an old thread but I just wanted to stop in and say thank you! I was having trouble finding XPS in enough quantities at our local big box stores. They could get, but it would take a little while to bring it in. Found this post, called our local ABC roofing location, and they had polyiso for almost half what the big box stores were selling the XPS. I'm thilled!
