Do your Wal Marts stock handgun ammunition right on the shelves? Because, now that I think about it, I think mine keeps it all behind the counter.
The best "deals" out there right now for larger quantities are the reloaders. Check Georgia Arms or Precision Cartridge. PC is in Hobart, IN so you would have to also pay state sales tax. I think last time I looked they may have stopped taking civvy orders. Both are advertising at least a six week backlog, but having a 1000 rounds show up on your doorstep for about $220 might look pretty good by then.
"I can't answer about Georgia Arms, but I CAN say that Precision Cartridge is still taking civilian orders. I emailed the guy about picking up some 9mm a week ago yesterday (A saturday) and got a prompt reply back within an hour I think saying yes he had it and to stop in on Monday. I walked in on Monday and walked out with a case (1K) of 115gr 9mm. Now I MAY have gotten lucky and he just happened to have a case sitting there. But I would contact them (call even) and inquire. If you live Close to Hobart, in (NW Indiana) then it might be worth a trip up to get it. The prices are VERY reasonably. The only catch is you have to buy in lots of 1K
