I hear that from other people, too. I do hit a lot of sales some weekends, but I also must live in a decent area, I guess. And my operating range is smaller than it used to be, because I get tired of driving to areas I don't know that well. Though, usually when I enter "Star wars" in garage sale listings, they come up outside my area in metro Detroit, which no matter how good looking the items, it never seems worth the drive (plus my knowledge of metro Detroit is limited). Some weekends are mostly a waste of gas.
I never mention GI JOE stuff and other toys I find. LOL. It's all pretty random. Not everything is cheap. And there's sales like one a couple months ago, the guy had 80's Transformers but he wanted decent money for them, more than I was willing to pay...because I don't collect them and am not up on their resell value. So I wind up buying $20 for some assorted 80's GI JOE parts, 2 loose figures and couple of incomplete vehicles, later thinking I might've done better with on ebay!
I buy things to resell, war games and rpg's. And model kits if they are cheap price, because kits are freaking expensive for what they are. We complain about toy prices, but kits you do all the work and some are $20+ for parts on sprues.
