YSK Some websites monitor your browser history and raise the price of things or flights after repeated viewings. To avoid this, surf incognito, remove your cookies, or use a VPN. Why YSK: It is important to know about these tactics used by some websites because they can significantly impact the price you pay for goods or services. By monitoring your browser history and raising prices based on repeated viewings, these websites can take advantage of your interest in a particular product or service and charge you a higher price. By using incognito mode, deleting cookies, or using a virtual private network (VPN), you can keep your browsing from being tracked and possibly avoid being charged more because of it. This can help you save money and ensure that you are paying a fair price for the goods or services you are interested in purchasing. Also, protecting your browsing history can help protect your privacy by stopping websites from collecting and using your personal information for targeted advertising or other purposes.
