Thank you

Joint account, he got 5%, I got 10%.

Yeah, that's why the Coop was specifically quoted in the comparison.

NUS discount does not work at Morrison's.

Also acc specific .

So, will this work if I just use my halifax clarity credit card in the shop or do I need to activate this?

Similar marketing incentive but with better value and longevity via another merchant.

How is this relevant to the deal posted?

Unfortunately it doesn't work on Santander. They see the cash back request as a separate transaction. I've got lloyds, halifax and Santander accounts

If you are sneaky it also pays out on cashback requests. I've always asked for £50 cashback on top of my grocery spend at the till and that tracks as part of the overall spend.

Only offers me 5% on my Halifax app!

Permanent 10% off, further 5% back and 1% to community via combination of Cooperative Card and NUS extra card, and you don't need to be a student: even cats qualify.

Thanks for posting OP, would not have known if you hadnt said something.

Its been there for sometime..
