Absolutely right, it's a good question. I don't think you could come into Dropbox's position without having someone on your team who knows this, but if you didn't, the answer could save you millions ;) But even for smaller amounts, if you sell 150K of goods per year through a reseller, and you pay a standard fee, it never hurts to e-mail them and negotiate a tighter deal. If you manage to shave off 1%, that's $1500 (clean profit). Say you pay 5%, you can apply pressure by saying you could get a better deal somewhere else, or implement their service yourself for that money.
