I am not sure how much I can express my love for this extension. This extension has helped save me so much money that I would not know that I was spending without it. I helps me know if items are actually on sale or whether there was deceptive practices to manipulate consumers into doing things that they may not fully understand. I am someone who tries to live as transparently as I can and this helps me understand consumer practices and allows me increase my spending power on ways that would benefit myself and my community rather than naively falling for marketing and corporate tactics.
