Shitsenders does exactly what the name says. They collect some nice poo, package it and send it to a friend of yours. You can choose between a variety of dung (cow, elephant or gorilla) - depending on your level of friendship and depth of message you want to send.
The price? About 20 to 30 US Dollars. The effect on the receiving end? Priceless …
*I will not mention your name - but thanks for sending in that shit*
