Valentines in August (VIA) is an annual event held by the organization that celebrates the idea of love and Valentines with an economic twist. As August is the farthest month away from February, the demand for flowers is at its lowest. Therefore, the idea of this project is to create an artificial demand for these flowers to compensate for their seasonal trough. Evidently, this event is usually held in August with a month of preparations done in advance.

Valentines in August has been a running flagship project for over 30 years.
