SQL PERCENTILE_CONT over daily-best per-product-per-day observed in-stock prices
Case quantities of .40 S&W — typically 500 to 1,000 rounds — are where the lowest per-round prices appear in the market. The gap between the lowest listed price and the market midpoint reflects the range between bulk-priced range ammo and premium defensive loads. Buying at the low end of the market means buying at case quantities, usually FMJ-class loads from volume-focused retailers.
Free shipping thresholds ($99–$150 on most major online retailers) typically align with case-quantity order sizes, which removes the shipping cost that can otherwise erase per-round savings. IronScout monitors prices before shipping — to calculate the fully-delivered cost per round, factor in each retailer's shipping threshold against your order size.
