3. Box Of Shit
Get them a gift to match both their personality and how they treated you throughout your entire relationship, have an actual box of real life shit sent directly to their house. The fecal angels at shitexpress.com will anonymously send the person of your choice a smelly surprise by post; all you have to do is choose your favourite from the wide variety of animal excrement, give them some money, hand over the address and the rest is up to them.
The very observant may have noticed that we used this idea for our Christmas gift guide but we figured it’d be fine to recycle the crap box as the sentiment still stands.
