content: I ordered the Penguin edition for this book five weeks before my grad class started. It was very important to have the correct edition for proper pagination. I PAID for the Penguin edition. I GOT the $2 Dover Thrift edition three weeks later. When I called the distributor, he told me to email him to remind him to fix it, but he didn't ask me my name or my order number or anything to identify me from any other customer. I asked for an email address and he told me to look on my confirmation email. The email address from the confirmation email didn't work. I had to spend another $15 to get the correct edition of the book. I'd already paid more for the book that I got than it would have been worth brand new. I will NOT purchase from this distributor again.
