Do you hate paying more because you live in Australia and not the US or Europe ? (I.e. Harry Potter is AUD$4.39) I have bought (I'm a Sydneysider) from these guys on 5 separate occasions and never had a problem.
There are more games than those in the link, i have just limited to the games for less than AUD$5.00.
NOTE: If you do buy a game please ensure that it is supported in "World" region as some games are region locked, you can see where it is applicable in the game details screen.
How they work is they buy games from anywhere in the world, whichever has the cheapest price when on sale and then offer to anyone anywhere in the world for a small margin. Basically it negates these people charging Aussies more for games. You can sit on whatever side of the fence you like on this argument but don't complain about being overcharged because you live in Australia if you wont take up these deals…. I am not affliated nor associated with any key resellers but have researched the topic and am frustrated by some peoples negative opinion of it (Typically these opinions come from people in countries where they aren't gouged for games like the US)
The downside is that these games are cheap in some countries where gamers cannot afford to pay much for any game. As i see it this doesn't give them a right to overcharge me, overcharge the Yanks for a change and we will pay local full price.
Have at it but don't be scared to use this site. Be careful if you go elsewhere though, G2A.com has had some very negative reviews as the site links you with an individual to buy from and not the site. Good Luck Aussies….
Store in title, OP.
