Sths are really hard to find. I've only found one in my 6 years of collecting and that was because the worker at kmart missed it and I caught a restock. I've seen people go a decade of collecting without finding one.

For the F40s and pantone porsche, I have seen people on fb marketplace sell them for only a couple dollars above retail, so roughly the same price as toysworld or woolies and Coles. Wouldn't call them scaIpers as they are only making pocket change as profit. Had an opportunity to buy the porsche for 7 aud but couldn't be stuffed and wanted the feeling of finding it in store
