Bling those games

I'm weird about inserts, as in, I want them. Cardboard trenches and baggies do nothing for me. I want to be able to set up a game and play as quick as possible. That said, what do you do for inserts?

I've made foam core ones before, and they're fine, but they just take so long.

On the other hand, buying them online feels like a waste of money because I could just make them myself?

What are y'all's go-tos, if any, for inserts?

I'm curious what y'all keep around to bling out your games. I am specifically talking about stuff that is not for one specific game. For example I keep some organizing aids (baggies, plano boxes, etc) around. I also keep small Styrofoam adhesive dots around. I put them in the inside of a few of my game boxes to keep the lid more securely fastened. 

What do you keep around for your games? Poker chips? Metal coins? Or?
