A little while ago GameStop put up some Vita memory cards at what can only be described as excessive prices. You'd have had to spend $30 for the smallest size and $120 for the biggest and this caused something of a mini-riot on the internet with people dropping pre-orders and screaming things like "if you're real, why are you making me suffer?" at the sky.
Turns out that GameStop, wait for it, were wrong when they announced those prices, overcharging in some cases by over 20%.
The image above, from SonyRumors, shows the official pricing and, while still not fantastic prices, gives some indication as to what you'll be spending to extend your memory in the new year.
