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
