Darkroom louvers / vents in Canada?

Hey guys, I've been after a couple of those spiffy Adorama/Doran darkroom louvres[1] but the only ones I can find online are in the US, and it'll cost me upwards of $50 to ship the bastards up here, yet they cost only $50 so that's pretty steep. I called some photo places here but they don't have any. Does anyone know where the hell I can find some of these in Canada? Surely people in Toronto and Vancouver take photos too. Any online Canadian photo stores?

I just want to get more fresh air to my plants man and for some reason the US has a stranglehold on the vent market. ;) I don't think we're consuming enough in Canada. I should be able to find a 50 pack of these at Costco for fuck's sake. /rant :wtf: :)

TIA

[1] Mentioned all over here by jamstigator, 311212 Adorama / Doran Heavy Duty Darkroom Light Tight Louvers, 12"X12" they only ship with UPS and I'll get stuck with import duties & shit, not cool! ... you can get them at amazon.com (won't ship them to us canucks), Digital Cameras, Camcorders, TV's, Home Theater, DVD Players, Apple iPods has them (thanks jam) ... but I'd end up paying $111 for 1, $175 for 2, $304 for 4 ... OUCH :(
