Cheaper grape's and olive's.
Price: Grapes cost 10$ per unit, Olives 13$ per unit.
This is approximately 90 percent cheaper then the ingame version.
If you think they are to cheap, you can also use fore example 50% of the ingame and 50% of this version.
Note: if you have the mod "Free Fences And Bushes" (for pc/mac) installed, then this mod does not do anything extra, as grape and olive's are ingame the same as fences.
