I recently realised that I don't even need to use up my dwindling supply of former grocery now mostly garbage bags for smaller garbage cans around my place. Previously, I would remove the bag from the bin, tie it up and drop it in the main garbage, usually after emptying it because otherwise it would be too full (and I'm in a condo with a dumpster, so timing garbage pickups isn't an issue).

My new method is to just grab the whole smaller bin and dump the contents out into the main bin, reusing the bag unless it got destroyed since it was last emptied. My main bin is my kitchen bin, so the others are mostly getting dry things anyways. It's the adhesives that can mess up the bags now, though if it's just a piece of sticky paper, could just leave it stuck to the bag for a while if it isn't interfering with other things going in.

I've been using fancier store bags (sometimes the reusable plastic ones, sometimes the paper ones that already look like gift bags just with the store name instead of Elsa or whatever) as gift bags, mostly because buying special packaging for gifts is just a waste, especially because the kid only cares about what's on the bag until they can get at what's in the bag, then it usually sits somewhere maybe holding a bunch of gifts for a bit, probably getting ripped before it gets folded flat to be used in the future, though I'm sure some people just throw them out.
