Tide to Go. Less than $10 for a 3-pack and saved my ass whenever my klutz self gets into minor accidents that lead to stained clothes.

A shoe horn, assuming you wear shoes. Longer is better unless you like to bend over.

Single guys that are interested in women, things to buy for a potential female visitor:

• a variety of tampons and maxi pads
• two types of moisturizer that aren't for jackin
• lady's first razor, shaving cream, potentially a hand mirror
• an assortment of travel hygiene products: toothbrush in package, travel toothpaste, mouth and wash, travel size whatever
• decent towels, hand towels, bath mat, etc.
• a variety of otc drugs: acetaminophen, ibuprofen, excedrin, and first aid kit.

Make your home welcoming to a potential visitor, and stock it with things they may wish they had, or they need and may be shy to admit it.

I think that's about $100

A dollar

This Baseus USB C 65 Watt 3-port charger. I recently bought one to carry in my laptop bag as a portable charger, and it has proven to be indispensable. I've already used it while out and about or on trips out of town to simultaneously charge 3 devices at once. Such as my phone, earbuds, and laptop. It's so small and lightweight, and you can bring a single charging brick to take care of all your devices. I'm never going back to having to carry multiple chargers with me.
