Depends entirely on where you are. I live near Charlottesville VA, and there is plenty of it around here, both FMJ and JHP. One store I was in last weekend had dozens of boxes on the shelves - Remington, Blazer, Fiocchi, Independence, Speer. I picked up a few boxes of Rem. Golden Sabres, but there was plenty still on the shelf after I took my share.
Even the price seems to have come down some from what it was near the end of 2009. Still pricey, and nowhere near the $11-$12 per box of 50 for 9mm FMJ, but dropping all the same. Around here at least, .45acp is easily the most expensive calibre these days.
From posts here and other forums though, some areas seem pretty dry still on .380, so you should check the stores you actually frequent as your region could be very different from others.
P.S. I buy my ammo in local private gun stores, not chains, so I don't have any idea how our local WalMarts or Dick's Sports and such stand for any caliber - price or availablity.
