This set of Spencer/Amos Eighth Edition Contemporary Microeconomics textbook and Study Guide are from a non-smoking home. The first 6 pages of the workbook are filled out, but the rest of it is blank. The textbook is unmarked (except for small scribble first inside page, pictured), but both have some cover wear and corner wear, plus scuffing to first couple pages. Pleas see photos. They were published by Worth in 1993. ---------------------------------------------------------------------------- Shipping is for the books carefully wrapped in protective plastic and heavy paper sent Media Mail with tracking. I recycle packaging to save us both money.
