Can't comment on the ad you mention as I haven't seen it yet. I was pretty staggered to receive an email from Tesco, excitedly informing me that it contained a preview of their Christmas ad!!! Needless to say, I deleted it immediately (without watching the ad of course). Why would they labour under the misapprehension that their customers would be that interested or concerned? I hate to have to tell you this, large retailers, but I, for one (and I suspect quite a few other people too) are deeply uninterested in your Christmas ads. The amount of money spent on them must be quite ridiculous and they have no effect whatsoever on my purchasing decisions.
