Personally, I prefer Save-a-Lot over Aldi, but that's just me. You might try www.mygrocerydeal.com (or is it www.mygrocerydeals.com ?) Enter your zip, and they'll list all the groceries in your area, as well as weekly specials. It's free to sign up, too.
I haven't been in save-a-lot lately but, my favorite store is Aldi. They carry many generic items that are just as good as name brands foods. I'm sure they are in Philly, go to www.aldifoods.com and search with your zip. I live over the bridge in NJ and do most of my shopping at Aldi.
