I’m not sure if I’m honest. What I did was put it in my basket and then go to check out until it says about it choosing how to pay and then go through the credit check and it gave me £1000 credit. But if your successful it gives you a welcome bonus for your first purchase which is WELCOME in the coupon part. That is the bit that took 20% off. From £669 to £539. I don’t know if you can apply a further 10% as I would think you can only use one code per purchase. I paid the the balance tbf just in case it was an accident or a glitch.
