Most of mine have been listed but..
Dollar store - pop up hamper, nightlight for bathroom
Roku
Echo dot - music, white noise
Ziploc bags in a variety of sizes.
Those washcloths that are packaged like pucks. I put one in a ziploc and when it gets too hot ask for ice at a QS counter and boom - ice pack/cool cloth
Tiny first aid kit with mole skin, Dayquil, ibuprofen, safety pins, etc
Laundry pods
fruit - costs too much at the parks and apples and oranges pack well.
