• 6-pack Diet Coke is sold out, but it works on Coca-Cola Zero, 16.9 fl oz, 6 Pack (dropping to 37 cents) or the Diet Coke Diet Soda, 12 fl oz Bottles, 8 Pack (dropping to $1.42).

Very YMMV, probably won't last long. Prime members only. Amazon has the 6-Pack 16.9oz Diet Coke Soda Bottles (Regular) for $4.99. Use the Save $5 on Groceries page to add the pictured 6-pack to cart, and checkout. It should be free and have free shipping (if you have Prime).
