Lindsay Shaw, 24, was walking downtown with a friend complaining about the price of tampons when she saw a young homeless person asking for money.

Shaw said that menstrual products are likely more of a challenge for homeless women because they are more expensive downtown “rather than the big box stores where you can buy in bulk,” and it’s difficult to carry large quantities.

A box of tampons or pads costs from $7 to $10. If a period costs a woman $20 a month, that adds up to $240 a year — not including new underwear or pain medication for cramps.
