Is it worth getting a Tesco Clubcard?

If you're ok with them using it to spy on you, it's a good deal.

Negger: do you dispute that they are spying on your purchases when you use it, or that it is a good scheme?

what makes you say they are spying on you?
they can tell what people are buying anyway, there is no need to focus on the people with clubcards.

the idea of the clubcard (and nectar etc...) are to offer you rewards for shopping there, meaning you are more likely to go back to tesco again.

Are you really that naive? Yes, they can tell what people are buying anyway, but not the demographics. It's the specification of which people are buying what that they want. Giving people the rewards is cheaper than paying for market research.

I'm not saying it's particularly malicious, but people should be aware of it happening.

ok, so what can they do with this information?

the worst they can do is give me advertising for stuff im going to buy anyway.

Like I say, it's not particularly malicious - they are using to refine their advertising and tailor your rewards.

I just think it's only fair that people know it happens.

so they can give me offers on things i buy, sounds good to me...

though i dont particuarly mind people knowing things about me (i never understood peoples thing against gmail searching your mail to give you appropriate adverts, again they are just advertising things i may want)

ZOMG!

Information such prefers coke to pepsi?

(i never understood peoples thing against gmail searching your mail to give you appropriate adverts, again they are just advertising things i may want)

I've sorta glanced through a leaflet but the rewards seem a bit hard to reach but I have barely looking into it, wondering if anyone has already and can tell me lol.

You must not send very sensitive emails, then. You might not personally have an issue but I don't see how you "can't understand" why people wouldn't want the content of their emails passed to advertising companies trying to build a profile on you.

the information isn't being sent on, a computer looks for key words, and gives an advert with matching tags.
