Thanks to somebody else on this forum posting in my SE425 vs. SE535 thread, I found out that http://www.electronicsforless.ca/ has both of them on sale! They're selling the SE425s for $279.99 (in both clear and bronze, though bronze isn't in the site - I just called) and the SE535s for $429.99.
I just called them to see how long the sale prices will last, and they said that the prices will last until they only have a few pairs left. I'm assuming that's soon because they only had 8 pairs of the SE425s left.
Free shipping Canada wide, but they also ship to the rest of the Northern Americas.
Hope this helps somebody! :)
