Ookong has almost always been one of my favorite firefox add-on's. However the latest version doesn't seem to be as reliable as some of the earlier versions for me. It often mixes up the marketplace price (NOT fulfilled by Amazon) with the Amazon price, and from time to time it doesn't show Amazon price history at all although Amazon has been selling the product itself. I'm not sure if these problems could be due to my ancient version of firefox (3.6.xx) but previous verions seem to have less such problems.
More comments after several days' use: 1. the tracked items' layout is hard to change. 2. I have several machines(including virtualized ones) . It is annoying to manage each of the browsers. Why can't you support account like the famous Xmarks?
It works great for regular Amazon items. But it fails to track quite a few things such as a car seat (for example Britax Marathon Convertible Car Seat) with different prices for different colors. The tracking icon simply won't show up for any of the choices.
It can save you a lot of money. Author is also very responsive to suggestions and I expect this will get even better. I tried another Amazon.com tracker and it disabled after a month (guess it needed a subscription). If you start using Ookong, you'll be amazed how much the prices on Amazon fluctuate for many items and you will definitely be able to save quite a bit of money by purchasing when an item hits a low point. Example- I got an mp3 player that typically is listed at around $180. One day only it dropped to $103 and I bought. It was back up to $180 the next day. Simple, unobtrusive, and effective. Don't shop without it!
I found this smart tool by chance. Frankly, I didn't pay attention to it because of its very small size, only 80k. I am a online shopping fan because it is easy, safe and tax-free. I think i have rich experiences for online shipping by analyzing the information from some deal websites. But sometimes it is very hard to decide when to buy a stuff because the price keeps floating. Although I used some tools to assist me to track the price change but they are not strong. After I choose Ookong, I find it really is a helpful utility for people who like online shopping. First, it provides the price change even very small amount, like 50 cents; Second, it is interface friendly. Once I install it, it is minimized in my Firefox window and pops up when price changes. Third, the price change curve is drawn for short-term like stock change which can assist my purchase decide. Of course, Ookong has its shortage that is the reason why I give it 4 stars. I spent more than 10 mins to find how to use it. Although it provides the online help, i am used to use the software without help. It is too sensitive to provide the small price change for example 50 cents. For me, 50 cents change is not very important to decide to buy something.
when i checked air ticket prices on kayak.com and saw their price history option, i thought price history should not only be available for gas and air tickets, especially for someone like me who spends much more time with electronics than traveling. this add-on works exactly the way i wanted and i look forward to its extension to other websites other than amazon.
