Doesn't seem to be accurate for me either. Not sure if they stopped updating or not.
I got 400rnds of 9mm yesterday at one, but they didn't have any 22lr or 5.56. Drove around to a few more today and they were all out of everything but .243, 30-06, 22mag, and .40. Except one, which also had the bulk packs (250) of .45 for over 200 bucks (i think).
