Now - let me tell you a couple cons of this site. She only matches with coupons that are found in Sunday's paper & from the basic coupon sites online. She does not match with competitors (if your store takes competitors) nor does she use coupons from the MF site directly. These are things you'll need to take into account when reviewing her lists. She may have coupons listed on there but not the higher value ones, always be sure to use the higher value :).
When you signed up be sure to tell them who referred you, I believe you have to give them my email address. The one I used for that site was email@example.com (note: I don't use this for personal emails, and rarely check that account anymore, so do not email me, I won't receive it).
