Small folding grocery carts that hold a couple full bags are available. If you need much more than that, a collapsible wagon will hold a whole shopping trip worth, and cost under $40.

I hate having to deal with the bum anti-theft wheel when pushing a shopping cart thru the store, but I admit I've seen people who take a cart home with them every week and just leave dozens of them there... can't ever be bothered to push even one of them back, so I guess making that bad behavior more of a hassle somehow is necessary.

Flexible drill bits are quite uncommon these days. First because modern brushless electric impacts are so short that it's easy to get into tight spaces that were formerly quite difficult with (much longer) electric drills. But more than that, you can just get a universal flexible extension bit holder that'll work with any size of hex drill bits you need to use. Though I'd say a right-angle drill adapter works a lot better in tight spots than a flexible one. With a flex, you have to use a drill smaller than the hole you need, because it flops around and enlarges the hole a bit, and quite a bit more effort to hold in place.
If you needed to do a lot of tight-spaces work, there are extra short, "stubby" impacts, as well as dedicated "right angle"/"close quarters" drills/impacts that'll make the job easier than using angle/swivel adapters.

Oh, that's barely getting started. Here's a short list with photos of a few dozen types of drill bits, which itself doesn't even get around to including the couple types I mentioned or several others I can think of (other lists will include mostly the same types, but a few different ones, too):

Merriam-Webster doesn't indicate any racist connotations to the word, and only the faintest hint there might be anything at all negative ("unorganized", "nomadic") about it:

horde noun ˈhȯrd 
1a : a political subdivision of central Asian nomads
1b : a people or tribe of nomadic life
2 : a large unorganized group of individuals : a teeming crowd or throng

Is that still a thing where you are? I haven't seen a single trick-or-treater knocking on doors in about a decade now. Apparently they are all going to organized (school?) events, due to the (completely false) myths of tainted candy.
