Couponing.....

FTM and I've always handled our finances and budgeting. Although I do it well, ever since finding out we are pregnant I've stressed over how expensive kids are lol. I'm really interested in getting into couponing big time. I thrive off sales and getting a good deal on things, its like a shopping high! Any tips from those with couponing experience? What are some easy ways to rack up on coupons for things, mostly baby items? Is there a way to have coupons sent by mail? Are there certain newspapers to buy? Any special couponing techniques?! Please tell me your secrets! 😍
