Based on your question, here are some of the best value 2 litre cold drink options I found in the PriceCheck search results: The Coca-cola Soft Drink Light 2.25L is available for just R21.99 per bottle. An even better deal is the Coca-cola Soft Drink Light 2.25L X 6 pack, which works out to only R21.32 per bottle. For something a bit different, the Mint & Lemon-lime Flavoured Sparkling Low Kilojoule Drink 2.25L can be found for R19.99. I hope one of these more affordable large format soft drink options works for you! Let me know if you need any other recommendations.
