As the half-gallon freezer bag... I had no idea what it was called until I searched "half of a gallon freezer bag" LOL.

I found the listing online, then all the sponsored links appeared. I picked Target, b/c they are well represented here in Detroit. Checked off the "pick up today" option, and it showed which stores had them in stock, and of course the store that was a par three from the house was it, after I'd been to the other side of town running errands.
