I don't know, at slojd-detaljer one can is 72 kronor and GMF:s can costs 129 kronor. I guess it also depends on how many cans you're buying, if I remember correctly there might be some lower price limit for buying, maybe like minimum 200 kronor or something like that. Is it possible for you to buy stuff through your school? Maybe you could buy directly from ernstp.se, they have all sorts of furniture supplies like nitro, fish glue, bone glue (translated from Swedish, is that the same as hide glue maybe?) and more. They seem to have a dealer in Suomi as well, have you checked http://www.rakennusapteekki.fi ?
Obviously the soundhole cap won't have a ivoroid back plate but otherwise it's the same cherry colour with binding. The jack plate and pickup covers got the same treatment as well.
