Get cash back at Costco. From May you will be able to purchase an executive card for £30 extra. you will get 2% cash back in vouchers for Costco. Its not public knowledge yet but will be made available soon. You can claim up to 2% of £15,000 so thats up to £300 per annum. excluded ciggies. So anyone buying anything that might get them enough cash back might want to wait till May. Only second post so please go easy, I might be able to answer questions though. Hope it helps some people.
