Most retailers will not fund points on the VAT element of a transaction or the delivery fees. Please refer to the retailer's terms and conditions to check if this applies. This can mean that you have a lower purchase amount reported and consequently a lower points amount.
If you really feel that your points value is significantly less than you were expecting - and this isn't accounted for by the VAT, delivery, and other such costs, then please contact our Member Services team by clicking here.
