I haven't had any issues finding Ammo (North-Central Florida). WalMart is always in stock (granted any 7.62x39 and .22LR bulk packs are very hit-or miss), and the Gander Mountain near me is basically at FULL STOCK. It still has .223 Wolf on the shelves. I used to have to buy the $14.99/20 Federal Packs, but it was a shame to shoot it through the WASR, and going there this Saturday, I found Golden Bear 7.62 for $7.99/20. Not pre-election, but still good, and they had PLENTY.
However, if you're having trouble finding it locally, the internet is your very best friend. JGSales, AmmunitiontoGo, NatchezSS, and others all have excellent deals on factory-new ammo, and the internet has recently had a large influx of brass-cased Yugoslavian milsurp which is cheap, accurate, and of high quality.
I wish I could say "support your local gun shop", but I can't, because I don't. With the absurd prices I've seen lately ($25/50 Blazer Brass .45), supporting them is more charity than anything.
