In St. Lucia, the cost of a 355ml Coca-Cola varies depending on where you purchase it, but the recommended retail price (RRP) is approximately $2.25 XCD (Eastern Caribbean Dollars). This is roughly equivalent to $0.85 USD. In a local supermarket, you might find it for slightly less, while in tourist-heavy areas like Soufrière or Rodney Bay, or at an upscale beach resort, you can expect to pay between $5.00 XCD and $10.00 XCD ($1.85 to $3.70 USD) for the same bottle. If you are buying in bulk at a grocery store, a 24-pack typically costs around $32.85 XCD. It is generally more economical to pay in the local Eastern Caribbean currency rather than U.S. Dollars, as merchants often use a less favorable exchange rate (typically 2.5 instead of the official 2.7) for cash transactions.
