The lowest price we recorded for Ground Zero Hero in the last 30 days, counting keys for every region, was $6.26. The lowest listed price for a key that activates in Canada is $6.26 today.
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.
Not all of them. Keys sold for another region (EUROPE, UNITED STATES) may not activate on an account registered in Canada; that applies to 2 of the 8 offers here. The cheapest key named above does.
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.
