 Sites related to purchasing the textbook:

• The UTSA bookstore.
  Consistent with UTSA's ``We will not be oversold'' policy ("If you can find the book more expensively priced, we will raise our price"), you probably don't want to buy the text here, but you might get an inexpensive used text. Remember that online prices don't have tax, but do have shipping costs -- it works out about even. UTSA's price is $?? new and $?? used (not including tax).

• Amazon.com's listing for the text.
  Our text is priced here at $84.95, used from $38. (No sales tax, but does not include shipping.)

• Brian's Book's listing for the text.
  Our text is priced here at $80.70. They have additional savings if you order more than one text, for example, 2 books at $76.45 each. I have not used Brian's Book's, so I can't vouch for them. (Does not include shipping.)
