New mom, need help getting started

While I've been wanting to start couponing for a while I just haven't had the necessary fire under my butt to ignite the flame to start, I guess you could say. Well, I have a son that'll be here on Tuesday and while I'm prepared for the first month or so....after that I'd like to be able to not spend a fortune if possible.

I need to start this but I don't even know how to or where to begin! I don't have a printer so I can't print coupons out...what are some other things I can do to get coupons and start saving the max amount of money possible? What are some apps, tips and tricks to this?

I'm sure there are posts similar to mine all over the place. If there is a post that someone's already made on here about this and you feel the answers are all available there then please redirect me to read the post. :) I'd appreciate it.
