Well here's another idea that you wish that you would've thought up first... maybe.
Ever been so annoyed with someone that you would do anything to get back at them, so annoyed that maybe they deserve poop through the post in a well displayed box? Well thanks to shitexpress.com there's a way of doing just that, without even getting your hands dirty.
This is a genuine website. You might be thinking; "Surely they can't use real poo, can they?" Well, they can. You can even choose the animal in which you want your gift to come from, while maintaining full anonymity.
So, go ahead, right some wrongs.
