How do I know how much TOM Points I get by purchasing a certain product?

"The maximum amount of TOM Points for each product is always displayed beneath its actual Price, and is displayed with any ongoing promotion rates already applied. The more discounts applied to a product on your order, the less points you will receive from purchasing the product.

*Note: If a product/order is purchased entirely with TOM Points, then you will likely receive no TOM Points back from that purchase.
