I don't have much money, so I have just been searching online. I really think online you have a better chance finding the ammo you need at a decent price. Going to LGS isn't bad either.
But I have been searching, waiting for a good price. Found some 9mm for 28cents/round yesterday (1000 rounds), shipment got here today (NICE!). If I would've waited 1 hour, I found some 9mm for 20cents/round. I got too excited.
