This is not a lot in my case.
Had a letter in June saying that the two institutions had agreed that the product is no longer sustainable and would cease on 31 August.
This has duly happened and whilst it didn't mean much to the RSPB in my case I'm surprised that it has stopped. Maybe not enuf folk signed up - I joined in 2008 but don't know when it began.
Bad luck for the RSPB
I don't know of any other credit card which operates any similar wildlife scheme.
