To those that haven't seen this, Bud's Gun Shop is offering 1000 lots of 9mm 124 grain Blazer Brass FMJ for $268.99 with free shipping. I'm flush with 9mm now but that's the lowest price I recall seeing anytime recently.
SG Ammo has several brands of 9 mm hardball for $259.80 per 1000 including shipping. Lots of other commonly used ammo has come down in price as well, including rimfire. I recently got 5000 rounds of CCI Mini-Mag .22 LR shipped from Target Sports for $339, not too far from the pre-pandemic price.
