Prices last checked . Each is the price the store lists; marketplaces add a service fee at checkout.
Not always. Stores that sell their own keys, such as Steam and GOG, add no service fee, though sales tax is added at checkout in the US and Canada. Marketplaces add a service fee at checkout, and some payment methods add their own, so on a marketplace the total at checkout will be higher than the price listed here.
Official stores sell their own keys. Marketplaces and third-party sellers sell keys from other sellers: check the seller and the key’s region before you buy, and pay through the store’s own checkout.
