Evaluate the clarity and effectiveness of the excerpt below from a letter of complaint and answer the question that follows.
i purchased a kool action game system from bullseye on october 27, 2010 for $109.99. it seemed like a great price until i got it home and began trying to put the thing together. several parts are missing, and the store refuses to exchange the unit because it was on sale. it was not marked “as is,” so i expected a complete and functioning unit.
what, if anything, should be added to this excerpt to the reader address the concern?
