They are actually expanding their selection in a lot of areas. The goal is to be the Amazon.com of Canada...so you might not be too far off on the Unit bearings... It is all online only stuff, not in the stores and it comes directly from the vendors so Best Buy just gets a kickback for the sales, but has no overhead for the product.
They have Leatherman multi-tools on there now, duvet and pillow sets, bed frames...all kinds of crap.
