Call of Duty Black Ops 2 Wii U: $4 was $39.04
Batman Arkham City Armoured Edition Wii U: $4 was $19.04
Mass Effect 3 Special Edition Wii U : $4 was $29.15
Guitar Hero Live Rechargeable Battery Pack Universal: $15 was $34.95
Purchased at Munno Para SA store
About 10 copies each of Batman and Call of Duty left when I was there, a couple copies of Mass Effect and I purchased the last 2 battery packs on display at that store (possibly more out the back, guy said there should be a lot of stock around, if not this store then most other stores have stock showing)
Should be Nation wide, not available online.
If I can improve this post in any way please let me know, I am not good at these things.
