A server computer system comprises a communications module; a processor coupled with the communications module; and a memory coupled to the processor and storing processor-executable instructions which, when executed by the processor, configure the processor to during an active web session within a web browser executing on a computing device determine that a web page active within the web browser is eligible for loyalty point redemption; and send, via the communications module and to the computing device, a signal to modify the web page active within the web browser to display at least one selectable option associated with offsetting a purchase price of at least one item using loyalty points from a loyalty points account.
