Sainsbury clubcard points, how much are 2400 points "worth"

[serin]

Could I retire on the proceeds?

I think 500 points are worth £2.50 so 2000 points would be worth £10.

If I were you, I'd keep saving the points!
Have you looked on their site at all the ways to collect points.
I am currently on 5538 points. I had no idea I had so many so am looking on nectar.com to see how I can spend them!
