Processing online transactions

An online system comprising one or more processors and one or more memory devices storing executable instructions, the system configured to:

• receive through an Internet connection a request to create an order from a customer, the order including one or more items and one or more quantities for the one or more items of the order;
• receive, at a point of sale (POS) located in a physical store, at a first location, a cash payment for the order from the customer;
• receive a request for a cash refund for the order at a second location;
• and
• prevent usage of the online system to transfer funds from the customer to another party by evaluating proximity between the first location and the second location and when the proximity exceeds a distance threshold, prohibiting the cash refund at the second location, and when the proximity is less than the distance threshold, allowing the cash refund at the second location.
