I here about them all the time. And now it appears I actually need one for my homemade bator. So where do I get one. I heard walmart before, and I looked once, but wasn't sure where I was looking. what section of walmart? Are they in the baby section?
I have never found them at Walmart (and I've looked), but our Deals dollar store has them for $1. There was a post on here yesterday about how to make your own out of ziplock baggies and rubberbands.
Check your local dollar store and walmart in the cheap kids toy section.
I got lucky and found some cheap easter ones the other day ago at my grocery store for VERY cheap.
Those are the only places I have found them...OH! and maybe oriental trading company online...but then you usually have to order 649,000 of them all at once.
