I currently selling 2 stacks of Ender Pearls at a time for 10 rupees per double stack. That means you get 32 Ender Pearls for 10 rupees. They are being sold on my Utopia Res right near where you spawn in. Res # is 5138. I have a ton of these things and if you want to a larger amount then send me a message and let me know how many you need/want and what you are willing to pay and we can work something out. Look forward to doing business with you.
