Hello. I was thinking about joining this forum for some weeks and seeing this post spurred me to action. I've recently done a lot of research on magnet sources for a small run of projects at the workplace. You're right about Rockler being expensive. They priced out the highest of all the providers I looked at.
Lee Valley was the cheapest retailer that I could locate but I never checked the cross-border shipping rates.
K&J Magnetics is the place I recommend. At first glance it doesn't look like their prices are the cheapest but they do give lower rates for bulk sales. What's even better is that they are selling higher grades of magnets than Rockler (probably the other retailers as well). If you get their N52 line you can usually go with one size smaller magnet than the n35 grades sold elsewhere which means the overall cost is a little lower.
Check out the pull force calculator to see what grade and size will work the best for your project.
