How much is it to by all metallica albums?

As of my last update in September 2021, the total cost of purchasing all Metallica albums, excluding any special editions, compilations or live releases, on CD format would be approximately $150 - $200 USD. This may vary depending on the country and stores you purchase from. Some albums may be available at different price points, and availability may vary over time. It's always best to check with a reputable music retailer for the most up-to-date information on pricing and availability.
