Points earned are based on the total amount settled in each purchase. Accumulation of receipts for Points issuance is not allowed. For example, if you spend $80 for a certain purchase (80 Points earned), and after the transaction is settled, you spend $80 for another purchase (80 Points earned), the total Points accrued from the two purchases should be 160 rather than 170.
Points have to be redeemed in denomination of 20 points, which is equivalent to $1. For example, you can redeem 200 points to offset $10 from your purchase. A maximum 600 points can be redeemed per online transaction.
