I traded with Red_Lives on July 21. I sent my models in a timely manner, and have yet to receive anything. Our exact trade was:
6 Doom Reavers
Yuri the Axe
11 GK Terminators
I linked him to my list which listed that the GKs were a mixture of metal and plastic. One was a metal GK with psycannon new in the blister, never opened. After receiving my models, he told me that he didn't know they were metal, complained about the paint and refused to send me the full trade.
When he offered me significantly less, I asked him to send my models back. He wanted to keep some to cover his cost shipping them back to me. I told him that wasn't really how things worked, and here's where we are now.
I'm out 11 GKs and have nothing to show. A cautionary tale to other Dakka traders.
