 Stean says that he uses three online tools: 

CamelCamelCamel: A browser extension (Chrome, Safari, et al) for Amazon shoppers that claims it can give a person immediate insight into a product's pricing trends, and the ability to sign up for price drop alerts.

Honey and Rakuten: “For those with less than great memories, install an online price tracking tool to do the work for you,” Stearn told ConsumerAffairs.

“Honey helps you see if things are historically low, high or average, helping you decide if now or later is a good time to buy. Rakuten helps me get discounts on things I do want to buy, bringing the price down to something reasonable or even deal-level.”

If you’re not into widgets and extensions, then the old-fashioned homework pen and paper route will work just as well. To do that, Cid says there are two essentials:

Do Your Research: Compare prices across different retailers or websites to ensure that the discounted price is genuinely lower. Familiarizing yourself with the regular prices of products you’re interested in will help you spot a fake discount.

Track Prices: Keep track of prices for items you're interested in over time. This will help you identify whether a sale is genuinely offering a lower price. Use price-tracking browser extension tools or websites to check the historical prices of products to help you determine if the sale price is truly a discount.
