It's not like going to the super market. And it depends on more factors than price. E.g. Salesforce's competition status plays a role as well, also whatever the current power struggle between different Salesforce managers, etc.

Usually in a big-enough company the least efficient thing happens instead of the most efficient thing. But the advantage of the big company is that it can play bigger games than your average small company. And if a small company succeeds at playing bigger then you can still buy it. So despite what HR and your manager might tell you, efficiency is not as important for survival.
