Canadian Tire has 60% of of all their C and F clamps until Friday. I went in and bought;
2 - 24" F clamps
2 - 36" F clamps
5 - 5" C clamps
15 - 3" C clamps
10 - 2" C clamps
3 bags of 10 assorted spring clamps
$128.09 spent
$192.60 saved
I know they are Crappy Tire quality, but for intermittent and backup use, not a bad deal at all. They will work great for glue ups on a strip canoe.
