Don't think I can do anything now but just want to share my stupid mistake.
I usually prefer to buy physical copy version of the game from retail stores (JB Hi-Fi primarily) because I'd like to be able to trade it. Yesterday I was looking for Batman Arkham VR since I just got my PS VR set, while I couldn't find it on JB Hi-Fi I went to EB Games and the staff told me that they only sell digital version of the game. The staff told me that the game is $29.95, thinking it should be around the same price in PS network since they are all digital version of the game, I bought it on the spot without checking.
Later I found that the game was on sale on PS network and the price was $17.95 :( I went back to the shop and try to ask for a refund but the staff told me that they can't refund digital version of the game since I could have copied down the code, which is fair enough.. and then I asked for a price match, which can't be done as they only price match retail shops T-T
Don't make the same mistake I did!
Cheers
You're in the wrong place to warn people Most people here know you CHECK PRICES before you hand money over.
