The Premium Plus version, with the £150 annual fee, is offering 25,000 Avios instead of 18,000 Avios.
The basic, free, card is offering 9,000 Avios instead of 3,000 Avios.
My full review of the free card is here. This is actually the most improved deal jumping from 3,000 to 9,000 Avios.
You have until July 31st to take advantage of these offers.
