Just bought a cheap road bike of ebay and the Aluminium seatpost is stuck in the steel frame.

I got it for a really good price so don't really want my money back. It is currently upside down soaking with just wd40 as it was all i had so where can i buy ammonia from or should i just get a decent penetrating fluid such as plus gas.

You can use caustic soda too.
