Great advice. Other factors to take into account : if your silo is small or you don't have many crates in your shop, storage is gonna be an issue unless you lower your prices or the crop is in really high demand. If you specialize in something (be it a type of crop or selling crops at discounted prices) you may attract followers who'll always buy your stuff very quickly. You've created your own little market. No need for ads, then, and you can sell them at a fairly high price. Also high-level players don't really care about prices because money becomes less and less of an issue as you level up. Almost all crops can be sold pretty quickly at max price (except maybe for wheat and indigo I'd say).
