No sure where to post this, but am a bit confused. I stuck about 6.5k on my tesco mastercard last month. Clubcard vouchers have now come through, worth £38.50. That's going to give me 10k miles, which is on a par with amex earning rates.

The other odd thing was the earning was split in two. About 90% had come from tesco credit card, whilst the remainder was from tesco world mastercard.

Any ideas? Is there a promo on at the moment?

Thanks
