Not enough Gold?

I never seem to have enough gold to buy things that are needed. Anyone know where there might be some hidden large amounts? (Hoping for secret rooms like in Aveyond series). Thank you so much.

Just sell items like wings and honey or even extra meat - all stuff that you get from monsters, that should get you some cash. Also in Green Grass fields there is a well with 500G hidden in it...

Thank you for the info will look/try harder.
