Absolutely OUTSTANDING. I rarely write reviews for add-ons but CouponBirds has saved me so much money, time and time again. Tonight's purchase I didn't expect it to find any coupons, or if it did, maybe must $2-$3.00, but instead I saved $37.35 tonight. CouponBirds is fast, and it just keeps on digging up great discounts all over the web on my purchases. This add-on absolutely rocks!
