Here I thought Kroger owned Safeway. Turns out that merger was actually blocked. Albertsons owns Safeway and the merger between Albertsons and Kroger was blocked in Dec 2024.

I’m lazy and already have windows installed/know how to use it.

Are you looking to get them swapped over to 3 prong for general use or are you looking to get them grounded for something specific? If you just want to plug 3 prong devices in you could look at installing gfi/gfci outlets. You’d need to investigate your lines but installation is pretty easy. If you need the outlets grounded for specific use I believe you can run a simple copper wire. Might require more looking into since I’m not super familiar with that one.
