Last year, right before the election, local Bi-Mart stores (think miniature employee-owned Wal-Marts), always had dozens of 50-round boxes of Remington UMC 115-grain 9mm on the shelves at $11.99. About once per month, they'd do a week-long sale at $2 off all handgun ammo. That would make it $9.99/50 with no sales tax here in Oregon. No limits on quantity, either. Sigh...those were the days. Oh, and just for reference, American Eagle 55-grain FMJ 5.56 in boxes of 20 would go on sale every month for $5.99.
Now, if you can get in line on the right day, and the delivery truck happens to have those 2 products, they are $13.99 and $8.99, respectively. Other local stores sell them for $16.99 and $9.99, if you can find it. And you only get 2 boxes of each.
