Where is the safest place to buy Visa gift cards?

Can you please provide some insights on the safest platform to purchase Visa gift cards? I'm looking for a secure and reliable option to avoid any potential scams or fraudulent activities. Is there a specific online retailer or a well-known brick-and-mortar store that you would recommend? It would be great if you could also mention any precautions I should take to ensure a smooth and SAFE transaction.
