Where to find coupon match-ups

On the right hand column, I have a list of blogs that help me each week to match-up coupons with sales. Saves me a lot of time!! The ones with the biggest variety of stores are cherrypicker and stretchingabuck. If you want drugstore deals, you can always visit www.iheartcvs.com, www.iheartriteaid.com and www.iheartwags.com.
