Balance Bars, toilet paper, pet food, chew toys for the dog, batteries, cabin and engine air filters, deodorant, vacuum bags. As a one-off, we got a six-pack of replacement pads for our Shark. Our go-to filler item, if it's on sale: multi-packs of Colgate manual toothbrushes (for travel bags and overnight guests). We skip shipments if the prices aren't appealing or the weather's not right for a food delivery.
