I joined the Barclays Avios Rewards earlier today as a new Premier customer. I see Barclays has a cashback scheme similar to Lloyds/Halifax and Natwest/RBS, where you get cashback for shopping at high street retailers using your debit card. In the cashback section, there is a link to join the Barclays Blue Rewards but no mention of the Avios Rewards!

Does anyone know if the cashback scheme is available to Barclays Avios Rewards members?
Thanks.
