To reiterate, buying options in times of low volatility could prove to be advantageous should the volatility increase sharply. On the other hand, a lack of deviation in the price of the underlying asset will produce lower market volatility and even cheaper option premiums. Once again, pricing is relative and dynamic; "cheap" doesn't mean that it can't get "cheaper".
However, unless soybeans were priced at $15 per bushel in the market on the expiration date, the farmer had either gotten paid more than the prevailing market price or missed out on higher prices. If soybeans were priced at $13 per bushel at expiry, the farmer's $15 hedge would be $2 per bushel higher than the market price for a gain of $2,000,000. On the other hand, if soybeans were trading at $17 per bushel at expiry, the $15 selling price from the contract means the farmer would have missed out on an additional $2 per bushel profit.
Market expectations of commodity due to variations in demand and supply (If the market feels commodity may go up and traders are bullish about commodity, then forward prices are higher than forward parity price, whereas, if market feels that prices may go down then forward prices may be lesser) The expectations are mainly dependent on demand supply factoINR.
For example: Tomatoes are cheap in July and will be expensive in January, you can’t buy them in July and take delivery in January, since they will spoil before you can take advantage of January’s high prices. The July price will reflect tomato supply and demand in July. The forward price for January will reflect the market’s expectations of supply and demand in January. July tomatoes are effectively a different commodity from January tomatoes.
If a company locks in the price and the price increases, the manufacturer would have a profit on the commodity hedge. The profit from the hedge would offset the increased cost of purchasing the product. Also, the company could take delivery of the product or offset the futures contract pocketing the profit from the net difference between the purchase price and the sale price of the futures contracts.
The fee you are paying to buy the call option is called the premium (it's essentially the cost of buying the contract which will allow you to eventually buy the stock or security). In this sense, the premium of the call option is sort of like a down-payment like you would place on a house or car. When purchasing a call option, you agree with the seller on a strike price and are given the option to buy the security at a predetermined price (which doesn't change until the contract expires).
