Where to get scrap insulation foam?

[RobertInOntario]

The big box stores might have broken or damaged pieces - I got some full sized sheets that had been crushed slightly in one corner (making the shiplap useless) for $5 each instead of $20.
In new homes, it gets used commonly for foundation insulation, so try your local subdivision under construction (just ask first...!).
Other uses include under interlocking stone (commercial projects usually), ceilings, basement floors so you might see if there's any renos going on nearby.
I almost always see large chunks along the highway too, so that's your last resort...!

Thanks, Andrew. I like the idea of trying the local big box stores. But I'm not sure what my wife would think if I started picking up scraps along the highway, although that would work too! I'll have to do this when I'm on my own!

Cheers,
