Crystal Pepsi is coming back on the shelves after almost twenty years.The clear soda, which was popular in the 90’s is back for a limited time beginning August 8th. Pepsi will also reintroduce their Diet Pepsi with Aspartame after changing that formula last year. Go Pepsi !!! Crystal Pepsi was great when it first came out, but then other beverage companies came out with clear sodas as well, which is why Pepsi stopped making Crystal Pepsi.
