I'm ashamed to say that I have never really used these
and don't really know how to make the most of them. Assuming my knowledge is currently at zero, please could people explain how they actually use them and how to get the best value from them? I have tons of unspent nectar points and now shop regularly at Tesco.
I have a vague idea that I can spend the points on groceries, and that would be fine if I knew how to do it, but I also suspect that I could get more out of them if I used them for other things.
Please advise! Thank you so much.
