this is not a "what kind of tire" question...

i'm looking to buy new tires for my van, and would like to
shop around...
does anyone know of any good shops in either vancouver, calgary,
edmonton or points between???

i will be travelling from Whitehorse in two weeks, and these are 
the prices here:

Mich. "grip" 185/75R14 65PSI max-$148(on sale), $196(reg)(plus 7% tax)
unknown      195/75R14 65PSI max-$153.60 (plus 7% tax)

from Blaskin & Lane, Calgary Alberta
Conti. LS20 185/75R14 65PSI max-$117.45 (plus 7% tax)

if i could get phone numbers, i can call them myself...
(what is the p.tax in B.C. 9%?)

(inuvik guys : bring many spare tires with you)
