For every dollar you spend at Pick 'N Save, a percentage will be donated to Urban Day School. If you already have a Pick 'N Save Advantage Plus Savers Card, stop at the customer service counter and ask them to add on the UDS charity code.
Advantage Card charity code for UDS: 879140X
If you don't have a card already, it's free to sign up, just see an associate at the service counter and make sure to add the code in the corresponding box.
