Offered: Nothing to sell

That's a little bit tricky to be honest, a philosophical maze, incorporeality renders it indivisible (I think) - some might mistakenly think I am selling some 'air' (which is divisible) - but I am actually selling nothing (ie: I have nothing to sell) - so have nothing to divide.

(I think ?)

To be honest I am not even sure that there is a 'thing' (or a 'state') called nothing - I currently lean on the side of saying there is no such thing as 'nothing'.

But, yes if it doesn't shift by the end of the week I will split it.

I think you'll be ok with this Tynan. Set theory tells us that the empty set can be split into an infinte number of empty sets. However, each empty set will be literally the same thing.

Of course this means that each person wanting a part will have to make do with the whole thing instead, and each will have to suffer the ignominy of having the same thing as everyone else.
