Worthless marketing unless proven otherwise. So if you need 500 of something and get a quote, and then massdrop gets a quote, massdrop will get a better price because of what? Bullying because they are "massdrop"?Professional negotiations.
Note that in order for massdrop to get the buyers a better price, massdrop must spend time and resources "negotiating", motivated by a lower cut if they do their work well. They must be motivated to work in order to earn less.
