Shopping up North??

Can anybody recommend where to buy a plasma TV up north? I have been in Harvey Norman looking at their plasmas and I have my eye on a 42" Panasonic but before I go buying it I would like to head up North this weekend and see if I can make a saving as any leftover money would be put towards getting a ps3

Would appreciate any help
