I recently corresponded with transformerland.com about selling a decent-sized collection of vintage action figures from the 70s and 80s. They were fast at communicating. They were fair and transparent in their offer, and the offer they made was competitive and reasonable. In the end, I sold to a local collector for less than what transformerland.com offered just to avoid having to box and ship a collection consisting of several hundred items (probably a thousand little pieces if you count helmets, guns, backpacks, vehicles, etc). The collector even grumbled that with the last collection he tried to purchase, he was out-bid by transformerland.com. So this seems like a great company to deal with, at least on the front end when it comes to getting an initial offer. I can't speak to any more than that. But if you have a collection you're considering selling, reach out to them!
