Coupon ladies?

My new years resolution is to learn to coupon. With the cost of living going up, a baby on the way and wanting to be a better budget-er for my family I want to learn to coupon. I want to save money and spend wisely.

I've already looked at the Krazy coupon lady's website and done some reading. I have once tried printing coupons online and used them in the store. Sadly my coupons were denied. They didn't work. It was quite embarrassing.

I did so much reading on stacking coupons, but where do I even get these coupons? Do I have pay for the Sunday papers to get these coupons? Not to forget, coupon language is kinda confusing. I just downloaded cartwheel from Target. That's a start.

Any tips or advice from couponers are greatly appreciated.
