Vouch is a free browser plugin (for Firefox, Chrome and Safari) that automatically finds discount codes for the website you're shopping on, saving you the hassle of searching for codes yourself. It finds & applies the best discount code for you - and it's 100% free.
All you need to do is install the plugin and click the Vouch icon whenever it turns red! The plugin will then try each discount code for that store, in turn, until it finds a working code.
Remember: If there are multiple working discount codes, Couponize will apply the one with the biggest discount!
