Back in the late 70's when I first came out to Calif., all the major chains got into a price war on soda prices. This is when they still had 6 packs which now are limited to lesser known brands like Shasta and some special root beers. But the grocery chain Ralph's ended the war real quick on a Labor Day sale. Get this!! Buy one 6 pack of Pepsi for .49c, and get A FULL CASE FREE!!! No one challenged them after that!
