Amazing how much people miss. For a while, you could go to several Kaybee toys, Johnnys Toys, TRUS, The Earth Toymall, Queen City Comics, Fairfield Hobby Shop, Tuesday Morning, and Big Lots, and find more than you could hope to buy.
Now, you have Big Lots carrying only PTE during the Fall season, Barbie and off brands of 1/6, sometimes getting blowouts of things like the Ghost Busters Collectors Mattel stuff. Johnnys is gone, Kaybee too, TRUS almost never has anything except Barbie like stuff, The Earth is gone and the Fairfield Hobby shop is gone.
it's hit or miss at Tuesday Morning, Queen City Comics can order from Diamond Select if they have stuff in stock, there is a hobby shop in Northern KY that carries 1/6, and some secondary market flea markets and antique / collectibles malls that have 1/6 stuff, and there is a niche market action figure store, but they have a very strange "all sales final" policy on even brand new defective merchandise, which by law as far as I can tell isn't right, but I just decided after one time with them, I just won't buy there again or recommend them either. You want to take a chance on a place like that, sadly I'll let you hunt them down and do business with them.
You just missed a big 2 day hobby show at EnterTRAINment Junction this month, and there was plenty of 1/6 scale stuff for sale there, from both private collectors and a true 1/6 scale store, the newly owned Toychest and Collectibles. The new owner is a member of the current SS-CC, so hook up with them again, and have access to that and the at large club members who are constantly selling, swapping, and buying as they like.
So, there you go, beside doing business online alone.
