Okay I ordered a used book from Amazon Marketplace. Unfortunately I bought the book from a seller and it was an older edition. The editioned I received was placed probably "mistakenly" in the 6th edition area.
I called Amazon, and they said to report the mistake by email. Then give the seller another 3-4 business days to respond. Then I could potentially get my money back. I am super unhappy with Amazon.
Their customer service sucks, their return policy is stupid, and they basically are useless. Why do I buy books from them? I really need to get the book but I'm now going to be stuck paying full price.
Sometimes I wonder if it is worth it? These online purchases seem perfect and too cheap to be true, and sometimes they are.
