Check out the PSA Ashley Greene and Justin Long filmed for Aeropostal’s Teen for Jeans campaign. Bring any pair of gently worn jeans to an Aeropostal between January 19th and February 14th and you’ll receive 25% off your next denim purchase. This is a great campaign. The idea is to collect as many jeans as possible to donate to the teenagers who are homeless across the US and Canada. You can read more about the campaign here.
