Loyalty cards..

[muddy]

I've had loyalty card for Sainsburys and Morrisons for a few years.  Also got a Sparks card from M &  S and a Tesco card,  The only one I havent got is Waitrose as I rarely go there - too expensive.

I have never got anything from the nectar card or the M and  S one .
Waitrose ditto .
Tesco sometimes gives me something off .

M&S Sparks used to give discounts, very few if any now.  I get some from Tesco, and a lot via my Nectar card!   Every week the offers get changed and you have to save them.

Nectar points can be spent in some places. Argos certainly and maybe Sainsbury (I don't shop there). I'm not sure if eBay still give them but they used to.

I mainly shop in Sainsburys, occasionally Argos.

I have an app called store which keeps my store cards on the phone as I am always forgetting where they are .
