You can access most of Gary Habermas' Credo Course on the Resurrection for free here. Free resources include the PowerPoint/Keynote, PDF of the workbook, and video and audio downloads. There is a cost if you want hard copies of the DVD's ($25) or workbook ($15). I don't see a deadline for the offer so you might want to act sooner rather than later. The website was a bit slow so you might need to be patient.
