I do a lot of my shopping online, and a majority of my purchases come from either Newegg or Amazon due to their competitive pricing and speedy shipping. The big problem I have is that prices change on these sites so frequently that it can be hard to know whether the price has recently been raised or lowered.
A free Chrome/Firefox extension called Camelizer makes figuring that out a lot easier. If you’re shopping on Amazon.com, BestBuy.com, Newegg.com, Backcountry.com, Overstock.com, or zZounds.com you can grab a quick price history chart for just about any item. One great example of when this can be useful is depicted in the screenshot above. You can see that Newegg is indicating the price of this particular computer memory “was $114.99″ and has dropped down to $89.99, and normally I’d have no way of knowing when that happened. With Camelizer I just click on the icon that appears in the address bar to instantly see a graph of the price history. Now I’m able to see that the price they’re referencing was from about 6-weeks ago, and had actually dropped to around $105 before it fell to the current price.
As you can imagine Camelizer is a great way to figure out how much money you’re really saving. If you decide that you want to holdout a bit you can set a price alert and Camelizer will send you an email or Twitter notification when the item drops below the threshold that you set.
