The program is sponsored by eScrip.
eScrip has over 150 merchant partners that will donate a percentage of your purchases to certain organizations, like Gloria Dei School. You register your grocery club card at the eScrip website, then shop for groceries like you normally do. A portion of each purchase (up to 4% at Safeway) comes to the school. You can also register your credit or debit cards, and any purchases at participating merchants with those cards will automatically be credited too.
Log on to http://www.escrip.com/ and click on "sign up". You can find Gloria Dei by name (Gloria Dei Lutheran Elementary School), ID# (119539873), city, or zip code (94002). Then register your Safeway Club Card --and your debit, ATM and credit cards if you wish.
No, the regular (paper) scrip program, where you buy prepaid "gift cards", is completely separate.
This program includes Safeway, Pak 'n Save, Draeger's, Lunardi's, Andronico's and Mollie Stone's, but not Albertson's. Look for a more information on how to sign up with Albertson's in a separate update, coming soon.
You can get credit for grocery purchases just by registering your grocery club cards. Entering your credit/debit cards enables credits from other listed merchants.
