With Freepost return for lost keys :-)
This service can cost a fair bit elsewhere but its available from Nectar for FREE.
Nectar to provide you with a key tag, on which is a 'If found please return to Nectar FREEPOST' address. This service costs a fair bit elsewhere but is free with Nectar.
Go to 'Your Account' online (or register if you haven't) and 'Request New Key Tag' from the menu on the left.
You can also request a Nectar Key Tag by calling Helpline team on 0870 4 100 100.
Following a successful trial in 2005 the Nectar Key Tag is seen as a more convenient way to collect points. It will ensure you don't miss out on points at times when you may not have your Nectar card with you as it attaches to your keys.
Hope this is of use to some :)
