The easiest and quickest way to save money while online shopping is by changing your virtual location to avoid price discrimination — the practice of adjusting the price of goods and services according to the buyer’s location. Getting around this is as simple as changing your IP address. . . Companies also assert price discrimination for return customers, charging you more if they know you’re more likely to buy something. By clearing your browser’s cache and cookies before changing your IP location, you can pretend to be a new customer and score big online deals.
