I know reloading in general doesnt essentially save you money, but enables you to shoot more (from what ive heard)

What are some things you guys do to help save $$ for your reloading costs?

do you always pick up empty cases at the range?

a tip/trick on saving cash on bullets/primers?

Im trying to come up with something I can show to the little lady that will make sense on paper so I can get started on it.

I'll probably start with 9mm, and I plan to build an AR at some point this year too.
