Did you have a Pop Shoppe nearby?
The Pop Shoppe began creating their own soda line back in 1969. They survived until the mid '80s when grocery stores began selling their own brands of soda at a discounted price. This began the infamous soda wars and The Pop Shoppe died. But, it is beginning to make a resurrection. Production resumed in 2004. They no longer refill the bottles for you as they once did. And, they are now using cane sugar rather than corn syrup.
