Haha, You can take my word for it, it's legit. But I do suggest you order a trial game, just so you know how long it takes for a game to arrive. You will receive it in 4-12 WORKING days (obviously excludes weekends). Max I've had to wait for is 15 days, weekends included. Generally, it takes more than a week to arrive.I was thinking this too, order some trial game or something, but I think you're trusted enough (I hope)
Also, if you're still in doubt, ozgameshop's games are all automatically insured. So if the game gets fucked up whilst in process of delivery from them to you, then you get a brand new copy for no charge. If the game gets lost by transport or w/e, you get a new copy for no charge. You may be thinking, "But that means anyone could abuse the system and just get infinite amount of games !!!11!!1". That's true, but, they trust you to not make false claims as they're already providing you games 50-60% cheaper than what it would cost you.
