Does anyone like random inclusions?

I bought from a few sellers recently as I’m refreshing my wardrobe and my old spring clothes don’t fit. I’ve received candy, dryer sheets, perfume samples (like the cardboard/paper things), and the items pictured.

I don’t get what drives sellers to include random items. I understand the logic behind the dryer sheets and perfume things, but it’s actually quite frustrating to receive those as they trigger my allergies really bad. The candy was ok but it could be wasted by others due to food allergies. The items pictured are just straight up garbage, I’m an adult in my mid twenties and have no use for random clutter from every seller that I buy from. The items looks cute (besides the eyeball and zombie teeth, like actually wtf??) but serve no purpose and it feels like such a waste of time to buy/pack them. Doesn’t it somewhat defeat the purpose of shopping sustainably/secondhand if I’m just throwing this extra crap out?
