You asked about getting refunds on games. I posted this somewhere, but thought I add it here too.
E.B. Games Store Policy.
If I buy a game for their asking price of $100 and see it within 7 days elsewhere for less. I can simply walk into E.B. Games and tell them/show proof via a catalogue or have E.B. Games phone the store with the cheaper price. They will then refund me the difference. I pre-ordered Thief at $100 and asked for a $30 refund upon picking the game up because another shop in the same shopping centre had it for $70 in their catologue. Even now, if I don't like it I can return it and get my other $70 back.
If I simply don't like the game for any reason. I can return it for a full refund. I love it as I can purchase any game and not be worried about wasting money if it sucks. Rambo is an incredible example, yet there is no way I'm buying that after what I've heard about it!
Noticed what you said about wanting to 1K Batman AO in Bigg's blog. If you ever get around to it and need one more person that won't be a hassle, count me in. I have most of the online achievements bar 1 or 2 and am more than happy to help you out.
