Title basically says it all.
I have a massive surplus of crops, so basically I just let them sit and maybe take a few when the chickens need feeding or such.
What is the best course of action in order to dispense of all this un-needed stuff.
Here's some numbers (Quality shouldn't be too important):
60+ Grids of Wheat
8+ Grids of pumpkins
30+ Grids of Flax
15+ Grids of Carrots.
30+ Grids of Grapes
10+ Grids of tobacco.
Not to mention close to 50 seeds of the above I don't use or need.
Edit: I should also mention none of my seeds are of trade-worthy quality.
