Most vendors should have them unless they specialize in certain goods - maybe try the merchants in Novac, Goodsprings, Mick&Ralphs in Freeside and Lacey at Mojave Outpost.

Or shoot ghouls, they sometimes carry bobby pins.

Edit:

This page from the fallout wiki lists some places where you can find/buy bobby pins:

Good luck!

You can also find them on any random medical box. If you are a bit careful with them and learn the small nuances of lockpicking (like go back when it is rattling too much and start over as it resets the pin strength, instead of wasting all of them on a harder lock), you can have more than enough in a few hours.
