I’m curious about how the metal cashback is calculated. Is it 0.1% of each transaction or of total spend? ie. if I make ten payments of £1 each, will I get 1p in cashback (0.1% of £10) or will I get zero cashback (0.1% of each transaction is less than 1p)?
This makes quite a big difference to the actual cashback rate you get, particularly if most of your transactions are <£50 in value.
