Re: Can I buy DA I from U.S to play in Bangladesh.
There are few ways to do so.
Buy a game key online (like g2a.com, maybe amazon? I believe those to be legit?) or through VPN through most other sites, but certainly not on Origin, as this is forbidden by their TOS and might ban you.
edit: I wouldn't even recommend your "friend" to buy it directly to your Origin account. Treated as VPN most likely. Key is safer way.
