Try the Society of Actuaries / Casualty Actuarial Society study resources [0] for exams P (probability) [1], FM (financial mathematics) [2], MFE (models for financial economics) [3] or S (statistics and probabilistic models) [4]. Look at the PDF syllabus documents, and there will be a section on "suggested texts". Looking up the suggested texts for previous test years (or for obsolete tests) may also reveal texts that may be cheaper now or available as used copies. You could probably get something like Price Theory and Applications (Landsburg) or Principles of Corporate Finance (Brealey, Myers, Allen) for cheap.
