Black Friday update

Here it is, midway through Amazon's self-declared Black Friday week in the UK, and the promotion is getting mixed reviews. Frustrated shoppers who weren't able to grab the most deeply-discounted deals are complaining to the Advertising Standards Authority about the limited amounts of merchandise available for brief periods.

Still, the possibility of buying a hit videogame or cutting-edge TV at a rock-bottom price is so attractive that Amazon's site and its Facebook page are attracting lots and lots of shoppers this week.

Will Black Friday be a plus or a minus for Amazon, after the week is over?
