Tesco very kindly sent my clubcard vouchers through last week enabling me to knock £43 off my shooping bill. They also told me I have £95 of unclaimed points on my account which I think might be due to one of my wives disposing of anything that looks like a circular as soon as she sees it. It prompts me to contact them and ask how I will be able to get hold of the £95 they've been looking after for me. All of this is very nice, but studying the other vouchers they sent, I was intrigued that thet were focussed on things we'd bought in the past, notably dog food and rabbit food, both in the Tesco brand we buy, and the pack sizes we buy. I commented on this with a colleague and she then checked to discover the vouchers she received were entirely different. She has neither a dog nor a rabbit so had vouchers for things she'd bought instead. I'm wondering if this is something to be worried about. Yes, it's great to get a quid each of dog and rabbit food, but where does it all go from here? The company is analysing our shoping habits on an individual basis. They know more about me than people who know me know. or to be more precise, are able to surmise more about me. Why are they taking so much trouble to make sure every little helps me personally?
