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.
