I think I can offer so more specific advice....

1500 Euros is exactly 2,119.46 Canadian... according to...http://www.xe.com/ucc/convert.cgi

Although prices vary in Canada, in BC, a quarter goes for 50, half for a 100... haven't bought in Oz's but I'd assume there's some discount for buying in bulk so probably $180

Even if there is no discount an ounce, of some high quality bud ( Im talking mild hallucinations in high doses), should not cost more than $200

If an Oz is $200 then 9 Oz's would be $1800... so I'd say your overpaying buy at least $319.46 and as much as $499.46 (If bulk discount happens)

Cheers,

P.S. Buy B.C!
