Hi there! Based on your request for a 2L Coke at the best price in the northern suburbs, I'd recommend the Original Less Sugar Soft Drink Bottle 2L for R25.99. It's one of the only direct matches for a 2L Coca Cola product in the search results. Getting a full 2L of crisp, refreshing Coke without all the sugar is a great deal. Hopefully this helps quench your thirst on a budget. Let me know if you need anything else - I'm still in training so my recommendations may not be perfect, but I'm happy to help further!
