I came across two cool firefox extensions that I’d like to share with you:

RetailMeNot

Did you know when buying items and services online there are often great discounts readily available?

During the payment process many online stores will have a field to enter a coupon or promotion code. Entering a special code will give you a discounted rate or free extras.

The firefox extension for this service will automatically informs you of sites retailmenot.com users have shared discount coupon codes for.
