Help sourcing humbucker magnets for a Canadian?

I want to try an A8 magnet, but I'm not sure where to source them. I saw Stewmac sells magnets but would rather buy from a non-american store. (No offense, i just want to avoid the crazy shipping fee with the tariffs if possible lol) And I know Amazon sells a lot of counterfeit stuff, so I don't know which sellers I can trust on there

Also, if anyone has tried putting an alnico 8 in a Seynour duncan custom 5 or in a p90, I'd love to hear your review !
