InvisibleHand Add-on Always Gets You the Lowest Price. InvisibleHand shows a discreet notification when the product you’re browsing can be bought for a lower price elsewhere. It gives you a link directly to the product page at the competing retailer.
It stays out of your way
InvisibleHand remains invisible until it finds a deal on a product you’re shopping for.
Unlike price comparison sites, InvisibleHand refreshes its prices every single time you use it.
It works with Google
When you google a product, InvisibleHand will automatically show the lowest real-time prices.
Reveal hidden prices
InvisibleHand knows the price even when the retailer tries to hide it (US only).
It learns as you use it
InvisibleHand will search for deals, even when you browse a product it hasn’t seen before.
