Many years back, there existed several online shops that bought modelers' collection of used kits. Does anyone know of any reputable ones now that I can sell to?

I could go the eBay route, and I've posted "For Sale" on forums, but I'm looking to sell these kits in bulk so I can ship just one or two boxes. I want someone who will pay for my entire "For Sale" stash.

They're mostly resin kits so I don't want to donate them to charity since these kits require someone who knows how to build resin kits.

Thanks in advance.

Here are two I know of to get your started. I've never sold anything to either though.

Thanks, exactly the kind of websites I'm looking for.
