Source for cheap 8 inch ducting

[Biologist]

Anyone know of good sources for 8 inch ducting that is a good price? I've got a lot of lights to hook up and don't want to break the bank. Where do you get yours?

Can't really say I'm a fan of Amazon but if you're looking to save cash I can't imagine anywhere is gonna be selling ducting cheaper than there.

You will want to buy it from a big lumber yard that is near you.
