Located in Brantford Ont. , and they ship almost next day via Canada Post.
No US BS about shipping, and their rates are real good...
I Highly recommend these guys... http://www.aircraftspruce.com/menus/ep/ducting.html
And they are cheaper too:
SCAT 3" is $9.50 /foot = $76.00 instead of $79.95 plus US shipping hassles & fees...
