I like the auto notice of discounts available when shopping. Just not sure how to access when they don't pop up!!!!!!!!

Gives often alternatives that do save some money. Sometimes the tradeoff in the offers don't make worth the small savings offered.

Excellent extension. Save me a lot of money! Thanks, Captial One!

This isn't perfect; sometimes it shows incorrect prices, it doesn't work on many sites, and you're giving up a lot of privacy. But you can save a pile of money when it does work; I just saved $20 on a $130 item when it pointed me to a 100%-rated ebay seller instead of Amazon.

Doesn't always jump right to lowest price but eventually gets there. Patience pays off!
