The only downside to this package? Currently it's only available in South Africa, where it sells for 399 Rand (or about $44). Perhaps if it's successful there, Blizzard will offer similar packages elsewhere, but for now, new players will need to purchase their game of choice and their antivirus software separately. And don't forget your authenticator!
