Thanks to Prime, I love to shop on Amazon, but how do I know I’m getting a good price? For the last year I’ve using a free Chrome extension called Amazon Price Tracker from keepa.com to view the price history of every product I order. Several times this has prevented me from impulse buying something because I noticed a recent spike in the price. The plugin allows you to set a target price and receive a notification, either by email, tweet, facebook post, or desktop notification when the product reaches your target price.
Right now I’m waiting for some laptop RAM to drop in price.
