Not sure if I am allowed to post links, if not i apologise, but you can buy them from http://www.beanbagrefill.com and they will ship anywhere in the US. I found them to tough to find in stores.

When you buy new appliances and electrontics, save the styrofoam(ask friends and family). tie it up in a clear garbage bag. When you are sitting in front of the TV, gently break it up in the bag. Then it's free! p.s.Make sure it is the pressed pellet forms!

I just added styrofoam packing peanuts to my son's bean bag chair when it got low. They worked, they were free, and you couldn't tell the difference. But his chair still had lots of those tiny beads in in. I'm not sure how they'd hold up if you used them alone.

Walmart used to carry empty bean bags and bags of filling. Last time I saw them was 2 or 3 years ago, so don't know if they still have them.
