Tesco Share & EarnI'm a Tesco customer and so rack up a few Clubcard points each week during my grocery shopping.  Whilst I've used their pioneering online store in the past as the shop is now local to me I go to it each week rather than making my food come to me.  Thus my relationship with Tesco is largely an offline one.

The retailer wants all that to change though.  They're offering customers a chance to earn Clubcard loyalty points by sharing and liking things on Facebook.  If you want to take part in the new scheme, you have to register to the Share & Earn Facebook app.

You then earn points by posting products they like on their own wall.  If friends then click through and buy those products both you and they earn extra Clubcard points for the purchase.

Matthew Entwistle, marketing director for general merchandise online at Tesco, said: "More and more of our customers are using Facebook to chat about and recommend products they like from Tesco Direct."

So this is basically an affiliate scheme for customers, but instead of earning cash you earn Clubcard points.  I'm quite happy to use Clubcard when I shop because I'd be doing it anyway, so in return for my buying information I get a bit of cashback in return.

With this however they're giving you a pretty small return.  Lets do the maths.  You earn 1 Clubcard point for each pound you spend in store.  That Clubcard point roughly equates to 1pence, so you're getting 1% back.  So this share & earn scheme appears to be an affiliate like scheme offering 1% commission on any business you generate through your sharing.

Given that I'm not particularly keen to pimp products on my Facebook wall anyway, a 1% bounty is not very likely to encourage me to do so.  So sorry Tesco, in this instance it'd need a bit more than a little to help.
