Kim Michalak says she ordered some household items from Walmart, things like pillows and cat food.
Instead, she received ten boxes of .22 caliber long rifle ammo-- and she didn't even have to sign for it.
She says Walmart won't take it back because her invoice lists the items she was supposed to get, but not the bullets.
On Tuesday night, Walmart said it is investigating how the munitions got to Michilak, since bullets aren't sold online.
In any case, the company will pick up the ammo.
