If you have 30 stacks of leather you obviously have a cow spawner. You're not running around wild collecting that much for 4k. If you have a cow spawner you probably have an auto cook/kill system on it and hopefully your smart and are collecting the results in hoppers.
If this is correct then you probably have way more leather and steak than you can possibly sell so i'm offer stands at 1.2k. If you got a double chest sitting around I might do 2k. No more for an item that is essentially limitless and effortless for you. That's like me demanding 5k for 30 stacks of cactus from my auto farm. No one will pay me that much.
