From their FAQ:

Is there some way I can force Elon Musk to pay $47 to Cards Against Humanity PAC?

Funny you should ask! If you’re a registered voter in PA, GA, NV, AZ, NC, WI, or MI, just type your name into this dumb website for his PAC, put “[email protected]” as your referrer, and they’ll be legally obligated to pay us $47. The more people who do this, the more Musk money we’ll get to un-fuck America.

If he doesn’t pay up, we’ll sue him again.

PM your Steam code and I’ll invite you. About to go to bed so it’ll be a while but I’ll get it sent sometime tomorrow.

I’ve always wondered why they use so many as well! I assume it’s each group of items that a single shopper pulls goes into one bag and they have one shopper per like four aisles or something. I have nothing to base that on though, whatever it is it’s a ridiculous amount of bags.

If you get delivery they will sometimes put three or four bags with a single item each all into another bag so they can carry it easier.
