Your points will appear in your Nectar account within 30 days. The reason for this, is that Nectar points are issued in line with our returns policy. You have 30 days to return most things – so that's why there's a delay before any new points show on your Nectar balance.
If your balance hasn't been updated in this time get in touch with our friendly Nectar colleagues, using the Nectar app or give them a call on 0344 811 0811.
