I had used honey in the past on another computer, but when I got a new computer I forgot to add it. I recently sw it mentioned and added it to Firefox.
I forget I have it. Even so it AUTOMATICALLY will search out and apply the best price, if possible. Otherwise it will tell me who has the best price!
This is an INCREDIBLY useful tool for anyone with more brains than money. If you don't care to get the best price available at that time, don't bother. Otherwise, DO IT! WOW!!
