Where and how to source copper pipe or used sanitary fittings in Canada?

[tiramisu]

Paying retail or worse paying retail plus shipping on some of the heavier piece parts would be fun if I had enough funds to just make a big order and wait for it to arrive but like most people, I am chronically tight for cash.

Where have you been able to find good prices on used pipe and fittings?

I'm in Winnipeg and my local Kijiji appears to be pretty useless.
Haven't found a canadian reseller for used sanitary fittings
and it seems like ebay sellers these days are more expensive rather than less expensive than retail.
The chinese prices are great till you factor in the shipping.

Any thoughts appreciated..

Thanks,
T.
