Walmart has excellent prices on ammunition. Winchester white box is reliable, accurate and effective ammunition for practice but is off sufficient quality to be used defensively. 11.50 for 100 rounds of WWB 9mm FMJ's is an excellent price. Walmarer also offers Blazer 9mm FMJ's in boxes of 50 and per 100 the price is similar to WWB, which is superior ammunition. They also have 250 round value packs of Remington UMC 115 grn FMJ's for 30.00. 300 rounds of WWB can be had for nearly the same price, but you get 50 extra rounds. They also sell 100 round packs of Remington 115grn JHP's, which is a great price for JHP pistol ammo. For SHTF, this might be a good route to go as they expand reliably and velocity is reasonable which equates to better lethality than a 9mm FMJ. The JHPs go for 13.00 per 100 rounds. They seem to have 1k+ of WWB and around the same of the Remington JHP's. If you have multiple Walmarts in your city, you could amass 3-4k between all of them. I try to buy 3-5 boxes of WWB 100 round value packs or WWB 147grn JHP's every time I go. If you order Wolf, Fiocchi or other ammo, the price could actually be more by the time you figure in shipping. WWB is excellent ammo, superior to other rounds in the price range and thier price is very reasonable. I have ordered ammo before, but I find it easier to buy WWB from Walmart as its cheaper/easier for me. The only exception has been ordering 2k of M882 from Ammoman.
