http://www.couponcodes4u.com to be a big help.
They've done a lot of the research fór me, and offer coupon codes, discount codes, promotional codes and free coupons. Sugar and spice and everything nice, all rolled into one website! Gotta love that.
Take for example their Hot Under Armour Coupons. Underarmour sells some great running skirts, and armed with my coupon I get a discount! Suddenly it's alright to splash out on that lovely pink skirt.
And if I feel the need to get away from it all, and make a run for it, they offer Top Bookit Promo Codes, so I can book my vacation with a discount.
It makes a girl want to run!
