Amazon is getting really fucking greedy.
Twitch Prime is losing its ad-free perk, and on Aug. 28th Prime Savings on game preorders is officially dead. They're replacing it with $10 credit for next purchase, and it's only going to apply to "select games" which is basically right back to the way things were 4 or 5 years ago. So any games you think there's any chance you'll buy on day 1, make sure to get the order placed this week. You can always cancel it later. Of course, Amazon is also currently pretending that physical copies of stuff like Spiderman and RDR2 don't exist so you're out of luck there.
Valkyria Chronicles 4 also has no Prime Savings at all for some stupid reason. I preordered and bitched at customer service, but all they did is give me a $15 credit. The product listing is still broken for everyone else. I've got half a mind to just cancel the order and GameFly it instead.
