$30 and change for a 333-round box of Federal LRHP, at the local hardware store. The local farm supply shop has been running 9mm parabellum ball ammo for under $10 a box, but not .22-yet. I'm waiting to see after the first of the New Year to see if a sale on rimfire for all those Christmas presents comes next.
FYI, those stocking up may wish to make note of two interesting container facts: As older cardboard *brick* 500-round containers become old and crumbly due to the acid content in the cardboard, they can pretty neatly be replaced with 16-ounce [empty!] peanut butter jars, which hold 500 rounds so nicely they might have been designed for the task. Those who buy poly bagged or bucketful .22 ammo may also find this info helpful.
Also: if those 500-round bricks of .22 ammo are not crumbly and deteriorating, ten of them package nicely in a ex-military M2A1 *.50 caliber* ammo can. It helps if the ammo is broken down into the 50 round boxes; it's a bit tight, but 5000 rounds will indeed fit- if they're in the cardboard 50-round boxes.
