Buying bundles on vacation

That's good to know then, but about some points:

• Bundle sites are often also key-sellers, like Humble Bundle, IndieGala and Bundle Stars.
• OP might be asking about buying from the Store part of those sites as well.
• Many of Nuuvem's keys can be activated and played outside of South America, even after the recent changes. There is a reason many people here bypass the restriction in order to buy there.

There's no such thing as TR region "keys", at least for Steam, anywhere. Turkey sells games officially only by retails which can only be activated on platforms like Origin and Windows Live at most.

They're usually sold by whatever the default currency for the site is and without any VAT. Because Turkey is Eurasian and yet not in European Union, nothing applies. You basically purchase a global version because you're out of specific options.

Humble Bundle will give you global keys, DIG will give you global keys. I didn't use any other bundle sites besides these but these two are trial-confirmed already by me.

TL;DR; TR doesn't have "keys". It uses global.

Update #1: Forgot to add, if TR actually had it's own region keys, you guys would have to pay for 18% VAT. So you guys better pray for my sake at least that this doesn't get to happen.

Update #2: This goes for bundles only. Steam purchases and gifts from Turkey will be region-locked. Because Steam was smart enough to not let the opportunity go.
