surely some places where you live got to be at least a little cheaper than that online and take money orders or something along these lines?
ever look into ebay? (but yeah, i know someone online i talk to in AU and it seems like stuff like this and computer hardware etc costs more there than it does in the USA etc )
p.s. also, what dvd burner brand do you have? ... because it might be possible someone would know of some generic discs (so there cheaper for you) that work with with your particular burner. but i just hope you have a decent burner because if you do i would assume there would have to be some discs other than Verbatim that would work for you.
but this is about all the advice i can think of at the moment. good luck
