I call them chop shops. I have spent way too much money on extra heads, body parts, guns, gun holsters, and other weapons like swords, from those shops. I have heads for GI Joe and Marvel figures I don't own. They're a customizers friend. But some of them can get expensive. And there was 1 guy, I'm not gonna name names, but he seemed all cool and stuff when we had a small issue, and then he gave me good feedback after it was all resolved and then blocked me from buying shit from him again. I was gonna too, he had more stuff I wanted. But alas, I guess I pissed him off or something. I unno.
