An anonymous heroine is winning widespread praise and social media acclaim for leaving out a box of pricey tampons at the Calgary Airport women鈥檚 washroom, in a gesture that led to a dramatic price cut on the cost of the feminine hygiene products.

The woman said in a note that she bought a box of 18 tampons from an airport vendor for $15, after discovering that the 50-cent tampon vending machines in the area were all empty. But, rather than taking the pricey box with her, the woman left it behind and scribbled a note for other tampon users.

鈥淚 was forced to buy this $15 box from Relay,鈥 she wrote in the note. 鈥淣ot acceptable! Please take one if you need one.鈥

The box of tampons shown in the photo are sold at for $3.97.

Traveller Carlee Field snapped a photo of the kind gesture and posted it to Reddit, where it soon rocketed up to the site鈥檚 front page as one of the most-liked images of the day.

鈥淟ady bro in the bathroom of the Calgary Airport! I appreciate you!鈥 Field wrote in her , which received a net total of more than 11,000 positive reactions.

鈥淚t鈥檚 so nice to bring attention toward kind things that people do,鈥 Field told CTV Calgary on Sunday, from her home in B.C. Field says she didn鈥檛 need any of the tampons herself, but she was still impressed by the generosity of the anonymous Good Samaritan. 鈥淔ifty per cent of the population needs these things and she helped make a difference that day,鈥 Field said.

Field鈥檚 Reddit post caught the eye of the Calgary Airport鈥檚 social media staff, who declared that tampon prices were being lowered in response to the issue.

鈥淥ur maintenance team has checked and filled all vending machines in the washrooms, and our retailer Relay has adjusted the price of tampons to $6.25, effective immediately,鈥 verified .

An airport spokesperson said the change was made in response to the Reddit post.

鈥淲e shared it with our partners and we were pleased to see our airport community come up with a solution,鈥 Dean Paddock, the airport鈥檚 director of corporate communications, said in a statement.

鈥淲hen we hear of ways we can collectively do better, we do.鈥

Field says she has just one message for the anonymous tampon provider: 鈥淭hank you. From woman to woman, you鈥檙e fantastic.鈥
