You may live in Romania but have registered your account in the UK. Or you live in Slovakia and have your Roblox account registered in the US. For a variety of reasons, you may want to buy a code from another region other than your home country.
To buy a code from another region,
1. Log into your Holyo account to see the products available in your country (here Czech Republic). Products are shown in the currency set to the country in which your account is registered.
2. Toggle to another country (i.e. USA)
3. Select the voucher you need. All products continue to be displayed in the currency that is applicable to the country in which your account is registered.
4. Continue with checkout to receive your code. You are billed in the currency that is applicable to the country in which your account is registered.
