I'm not sure if buying from the US is an option for you (shipping gets costly) but the big mail-order houses in New York (B&H and Adorama, among others) have grey-market Fuji Superia film, 135-36, for around $2 US per roll. I tend to buy about 40-50 rolls once a year (and the shipping ends up being more reasonable per roll; I also tend to order a few other things along with the film). Fresh film (generally a year and a half to two years before expiry) and longer rolls, too, plus it's film that's still produced so it doesn't drive the minilabs quite as insane to find the right channels.
I'd buy some Agfa film at the right price, but if I can get something still in production for close to the same price with a more distant expiry date, I would rather do that.
