How to get Portal 2 at the best price?
The price of Portal 2 can vary quite a bit by store, so it pays to check Steam alongside Instant Gaming and G2A. It's a low-priced title, so differences are smaller, but it's still worth a quick look before paying. With a Metacritic score of 90, it's one of the best-rated in its category, so locking in a good price is doubly worth it. It's also a few years old now (2011), so steep discounts are common. Always make sure the store is trustworthy and the key is valid for your region before paying.
