Ending today, Coupons.com offers a 1-year subscription to its Savings Club for free via coupon code "BIRTHDAY". That's $30 off and tied with our mention from two weeks ago as the best deal we've ever seen on this subscription. The Coupons.com Savings Club offers higher value coupons than for non-members, as well as a coupon finder to find coupons based on brand.
Note that you'll have to enter your credit card information and that it will auto renew after one year. Be sure to cancel before the renewal or you'll be charged $30 for another year.
