I am not convinced that Nectar is the same as the Grocery points. Reason being is that I've literally only just today been awarded for my first shop with Sainsburys which was from the 8th Feb. I am getting Nectar as that's a separate loyalty scheme. The Avios points appear as Sainsbury's Grocery OR Nectar to Avios. I've got a couple of names via LinkedIn as someone suggested - am emailing them today so will keep you posted on the outcome. There is definitely a glitch in the system!
