In-store only, Target retail locations offer the Disney Infinity: Starter Pack for PlayStation 3, Xbox 360, Nintendo Wii U, or Nintendo Wii for $29.99. (The link is for reference only; you'll have to make the purchase in a Target store.) That's the lowest price we could find for any platform by $25. It includes a Disney Infinity game, three play figures, Infinity Base, Infinity Power Disc, play set piece, and web code card.
Gamefly offers a selection of used PlayStation 3, PlayStation Vita, Xbox 360, and Xbox One games for sale, with prices starting as low as $8.99. Plus, most titles qualify for free shipping. Combined, that puts most titles well below the lowest total price we could find for their new, factory-sealed counterparts. A couple of best bets:
Amazon offers its Prime members Lightning Returns: Final Fantasy XIII for PlayStation 3 or Xbox 360 for $29.99 with free shipping. (Non-members can spend $35 to bag free shipping; otherwise it adds $4.98.) That's the lowest price we could find for either version by $2, although we saw the PS3 version for $2 less in April.
GameStop offers Final Fantasy X/X-2 HD Remaster for PlayStation 3 or PlayStation Vita for $19.99. (Amazon charges the same for Prime members.) Opt for in-store pickup to dodge the $3.50 shipping fee. That's tied with our mention from four weeks ago as the lowest price we've seen for this game on either platform. (It's also a current low for either platform by $8.)
