Better deals in Canadian store recommended by clarenix0813, details below

Good deal, but Let me propose a "slightly better" way to take advantage of this deal.

As of now, PSN canada store is having the same weekly sale, (well sort of)

I suggest buying canadian psn cards from amazon or from here(pcgamesupply.com) they are legit, tried them, and of course you have to have a canada psn account.

Note that CAD is just Slightly over AUD whereas 20 CAD PSN is just 20.23 AUD

Tomb Raider DE 8.25 CAD Cheaper

Thief 8.25 CAD Cheaper

Sleeping Dogs DE 12.5 CAD Cheaper

FC4 23.10 CAD 30 CAD for Gold Edition Cheaper as well.
