A. Many retailers, such as Amazon, Bestbuy, Walmart, use dynamic pricing tactics that charge higher prices to consumers on an item, once it figures that you might not mind paying a higher price for the item, based on your past online shopping behaviors.
To deal with such tactics, here are two tools consumers can use:
1. Camelcamelcamel: this is a good tool for people who shop at Amazon, it allows you to create price watches on Amazon products.
2. GetInvisibleHand: this tool is a browser extension, whenever you land on a page selling a product, it automatically searches the web for the lowest prices on the item.
