For PlayStation Plus members only, PlayStation Store offers downloads of Battlefield Hardline for PlayStation 4 or PlayStation 3 for $3.99. That's a slight drop from last month's mention and the lowest total price we've seen for this game. (It's the best deal now for either platform by $11.)
GameStop offers The Disgaea Triple Play Collection on PlayStation 3 for $21.97. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $4.99 shipping charge. That's the lowest price we could find by $7. It includes Disgaea 3: Absence of Justice, Disgaea 4: A Promise Unforgotten, and Disgaea D2: A Bright Darkness.
