i think they do. but i was just pointing out that if they have one and want the points then i think you get 2 for every £1 you spend. might be worth it if you can claim the money back or something, keeping the points!
If the shop gives them on every purchase then yes - if it is a link off the nectar site then the company will only pay referrals once - to either nectar or quido, depending on who you click-through.
