The most recent PlayStation Store update has quietly delivered five PS Vita titles—discoverable by search—that show the digital versions costing between $3 and $5 less than their retail versions.
Uncharted: Golden Abyss is listed for $45; it's $50 at retail. Modnation Racers: Road Trip comes in at $27 ($30 MSRP). Hot Shots Golf: World Invitational is $36 (versus $40 at retail.)
It's a discount off of the game's in-store price, but not the 40 percent speculated back in December, when people were freaking out about the price of PS Vita memory units. Of course, the official pricing on the memory sticks ended up being lower than originally feared, though the proprietary memory units are basically mandatory for anyone wishing to take advantage of the Vita's digital download service.
