Vodafone sent me a letter recently (to the wrong address - they've got the billing address sorted now, but it seems the snail-spam is still going to my old home) to let me know that their deal with Sainsbury's was ending, so I wouldn't be able to collect Nectar points from my phone bill any longer.
This wasn't actually a big deal since I no longer shop at Sainsbury's anyway, but their letter does highlight the perils of using mail merge.
With your points balance of 496 on account number etc etc etc why not treat yourself to a shopping spree at Debenhams, Argos or Sainsbury's?
Well, the answer to that is very simple. 496 points are worth absolutely nada. If I saved up another 4 points I would be able to get the minimum denomination voucher worth two pounds and fifty pence! Yes, that's worth about half a cheap bottle of wine!
