I love buying my minis on Craigslist and have even found some great deals at the local city flea market at the old drive-in theater.
A couple of weeks ago I picked up a new box of crypt ghouls, and a box of skeletons for a dollar for both.
Last weekend I was digging around and found a sandwich baggy with these old minis in it for 50 cents each.
The top row are fantasy, and 40k on bottom. The bottom right three I took a special interest in, plastic Scout? Chainsaw warrior, and 2nd pattern Terminator.
So keep your eyes peeled for Craigslist adds and hit up the local flea markets ( unless you live near me ) , you never know what you might find.
