I have a PS3 that I bought years ago. Never really used it as I am not a big gamer and I have no knowledge about Sony and how their store works. However, my son is now old enough to play video games and loves Minecraft. I was wondering if Sony has any type of discount codes or something similar to Google Play Store where you can earn some discounts or points or whatever program they have. Right now, he is interested in skins for Minecraft.
