- Rated 5 out of 5One of my favorite addons for Firefox. And it just gets better and better.
- Rated 5 out of 5That's a good one to get better prices! I hope this gets the five stars it deserves and continues getting better.
- Rated 4 out of 5very cool stuff.
- Rated 5 out of 5Fantastic Add-In, saves me a ton of time, when I am shopping for my tech and electronics stuff.
You will see a little alert if it finds other pricing and it is you choice whether to click on it and have a little Windows tell you the locations and pricing. Then just click and it will take you to the other vendor.
Jennifer, HOW the heck can it possibly include shipping costs and not take forever to come up and be brutal to look at ? Most places you have a choice on shipping and it varies depending on location. It can't be psychic.
- Rated 4 out of 5It's actually quite fun. Though as dakatone I had some strange things. But it definitely is worth a 4
- Rated 4 out of 5We always buy stuff online and this has been really great in helping us finding the best prices. I do wish that it would be able to take more into account the shipping costs though. Sometimes the lowest price doesn't include shipping, which when you add, can end up costing more than the next two or three things.
- Rated 1 out of 5NEW VERSION IS ADWARE!!!
Excellent and useful for comparing prices. Now, however, it has become a pop-up adware machine: When I looked up "North Carolina" on Wikipedia, I got a drop-down ad urging me to "Buy Big Bubba's Guide to North Carolina BBQ at Buy.com!" No thank you -- I uninstalled the extension. If future versions include an option to omit the drop-down ads, I'll try it. Until then, NOBODY WANTS MORE ADVERTISING IN THEIR BROWSER, EINSTEIN!!!
Developer responseposted 9 years agoPlease accept my apologies for the errant notification. InvisibleHand had mistaken that page for a book listing and shown a notification. This isn't supposed to happen, and we'll be fixing the issue within the next few days. InvisibleHand is not Adware. It only shows notifications when you're browsing a product. In this specific instance. it made an error, and we'll be fixing it imminently.
- Rated 2 out of 5The concept is wonderful, and when the plugin does actually work as expected it is also wonderful. However, it fails on many products that have complex product number differentiations and customizations resulting in different products. An example is laptop computers. The plugin keeps sending a message that the $2400 Macbook Pro I was looking at was available for $485. Needless to say it points to a Netbook on Amazon. It also, as specified by some, has issues when it comes to shipping. Granted this can be a tricky problem especially with sites such as Amazon where free shipping has dependencies.
All-in-all I give the idea behind the plugin 5 stars, but the current implementation drags the total rating down to 2 stars.
- Rated 1 out of 5nice concept ... but ... doesn't work at all... strange that it would be a featured plugin when its totally useless :(
- Rated 5 out of 5good
- Rated 1 out of 5Great idea but it doesn't separate the product price from any shipping fees. So most of the time it's wrong about which site is really the lowest priced. If I have to check five or six sites I really don't need this add on. Taking it off until they improve it.
- Rated 5 out of 5great!
- Rated 5 out of 5It a money saver and a fun one (well if you like shopping...)
- Rated 5 out of 5Marvelous add-on! Really saves money! One suggestion : Would be great if you could add a facility to add popular retailer sites in this.
- Rated 5 out of 5That's a good one to get better prices!
- Rated 5 out of 5Used to work. it doesn't work now. I went to Google, Amazon, and Best Buy... didn't get any notifications or pop-ups of special prices for items I looked at.
ff version- 3.6.8
- Rated 4 out of 5Can you add CANADA?? Would be great!
- Rated 4 out of 5I love this add-on, it saves me time and money.
I have Amazon Prime so a lot of times it tells me another site is cheaper when it is not after shipping.
If it was capable of calculation shipping/tax, like Google Shopping does, than it would stop directing me to other websites that end up having a higher grand total than Amazon Prime.
Even with that minor down fall, I still love it!
- Rated 5 out of 5Fantastic addon to help you quickly find cheaper prices. Ignore the review claiming it's intended to drive traffic to Amazon; it often directs me away from Amazon to other retailers with the item available for a lower cost.
- Rated 3 out of 5Strange- it doesn't work (nothing) for me. I went to Google, Amazon, and Best Buy... didn't get any notifications or pop-ups of special prices for items I looked at.
ff version- 3.6.8
- Rated 4 out of 5I buy 99% of all my stuff online, and this add-on saves me lots of time and money. A must have add-on for any online buyer.
However, sometimes it doesn't display the money thing (the thing under the tab).
- Rated 3 out of 5It works. Google Shopping works better though. When I do follow a link from Google Shopping, invisible hand actually pops up and tells me other prices, even though it doesn't ever mention the site I'm actually on. This is puzzling; if it knows enough to show me different prices, shouldn't it know that this is the best price, and tell me that from the beginning of my whole search?
However, this is only in some cases. It's still semi-useful.
- Rated 4 out of 5This is a GREAT little add-on, I buy almost everything on-line, have for years except food and clothes.This is the greatest little add-on since Xmarks. It's already saved me many bucks and the time it saves you from bouncing around the web searching for the best price blew me away. You wont regret this little jewel.
- Rated 4 out of 5let IH save you money at Staples. They meet competitors' prices, so through Amazon i found a price for somthing both stores carry but amazon was 9 dollars lower than staples, i brought the printout into the store, and got the lower price! woohoo!
- Rated 4 out of 5does not distinguish between after-rebate price and before-rebate price.
