The reason I like the idea is that when ththe are bonus promotions nectar can be worth more, cash is always worth the same, plus cash is easier to spend. I use nectar as a saving scheme So I can buy diesel when there is too much month at the end of the money!
I have been collecting nectar points for years but can never log on to my account to check how many I have there. Do they expire?
@harrybeau pop into a Sainsbury's store customer service will be able to tell you the nectar card balance.
