Wal-Mart has to be my favourite retailer (tho it's be interesting to see how Target does).
Wal-Mart prices here usually are comparable to the US counterpart for many items when I cross check my local store and Walmart.com - rare for the Canadian market.
I'm not sure why people are so hard on the value electronics sold there - the build quality is usualy find since Wal-Mart doesn't tolerate less from it's suppliers (and if they don't the supplier is gone).
I still have booting around here a 5 yr old Symphonic PVR with 80GB HDD and a Venturer HTiB that works great to this day. Just because one brand of value electronics is junky doesn't mean all are.
I also got my cellphone and computer from them without having to deal with that upsell or extended warranty harassment found at other retailers like Future Shop - and for a cheaper price than any other retailer.
