When purchasing a seed, the rule concerning bulk purchases will in most cases, directly apply. This means that it is often economical to buy a seed in larger numbers than in smaller ones. This is part of the reason why the seeds in hobbyist shops will often be a lot more expensive than what one would find at bulk agricultural suppliers. This is no longer too much of a problem thanks to the internet, which has revolutionized distribution in a way like never before. Not only is it cheaper to buy online, but more choices are often available as well.
