Dunham's, a sporting goods chain in Michigan, I don't know how far they are spread nationally, has Federal bulk 22's on sale.

1100 round box for $60 with a $10 rebate, you have to buy two boxes to get the rebate. $128 out the door for 2200 rounds, pre rebate isn't a bad price.

Picked up two boxes yesterday, probably pick up another two today. I shoot a hundred plus rounds of 22 each week and my pre panic stash is getting down to less than a lifetime supply. Time to restock.
