Call other store or go to web and order
Try Ross or Marshall's. They may not have large quantities or varieties of package sizes, but usually have Ghirardelli items, even Christmas flavors, at a great price. I found the extra large 20+ ounce bag of milk & dark peppermint bark mix for $9.99 at Ross near me. That's cheaper than a 10 oz bag at Walgreens.
They have them on their websites
