Replacing Debenhams Credit card

Casper7

We used to use two credit cards, Amex to collect Avios, and Debenhams CC to get points into vouchers to use in the the store, this card was used where they don't accept Amex.
Now Debenhams is gone (no points anymore), do you suggest any good Master Card?
I did some search and the ones available are really pathetic, some give me like half a penny for every £5 
We mainly shop at Asda, then some shopping with Tesco. So Sainsbury's or M&S might not worth it. I guess even Tesco's is not worth it.
The average spending on the Master Card (Non-Amex) is around £450 a month, and this would give me like 50p cashback !
I am currently using my Halifax Clarity card in non-amex purchases.

In the UK you'll struggle to find a better cash back card than Amex to be honest if that's what you are wanting?
Santander offer a MasterCard I think that offers 0.5% cash back

If you sign up to the MSE Credit Club, it will show you which cards you might be eligible for (assuming you have a decent credit history) and you can filter those to see which ones are Reward Cards. There were a few options when I checked the other day, but I agree with the poster above - Amex will definitely be the highest rewards.

The Amazon card from Newday offers points that convert into Amazon vouchers - you get more if you're a prime member. Sainsburys card offers nectar points and the odd bonus promotion from time to time. Barclaycard have a cash back card for 0.25%. There are a few options - but not very generous. It all depends on your credit history and those you might qualify for - all three that I've mentioned have eligibility checkers that you can use before making a full application.

I used the Debenhams card too and the ASDA card till it was withdrawn.  I am just using the John Lewis card for points instead. ASDA did say they hope to bring out a new card soon so maybe keep an eye out for that.

Thank you guys for your inputs... It seems I will stick with my Halifax Clarity card until something decent comes in.
I keep using my Amex as the main card but t is not accepted everywhere, that is why I was looking for a second option.
Thanks again
