You'll get 50,000. Don't listen to him. He will end up re listing it with some of his unsold items to move his products. If someone doesn't use the gin, it will definitely exceed 40,000.
Ha! lol. Gerod is correct with that. People like to hurry and bid so GIN's can't be added or changed, because a lot of people like that will lowball hoping that you don't know what you are doing. Good job staying strong. 50k is actually really good considering there is a Pokemon game included. If I had the credits right now I'd probably make the move on this, funny to offer a mere 10k less. I doubt he had any real intentions to spend the 40k for that matter.
