Book flipping take two

So, I found book that looked like it could turn a profit. Amazon offered a $120.01 credit for this book and I found it available for express shipping for under $35. I should be able to get that within about a week and send it out to Amazon, right?

No.

This ran me into a few hurdles. As of this writing, almost two weeks after ordering the book, USPS still doesn’t even show it’s shipped and repeated attempts to get anything from the seller have been unsatisfactory with them giving me the tracking number and me sending them back the USPS response that they’ve only been notified of the shipment. Add to this that Amazon gave me the credit already. Since there is no indication when the book will be showing up to me, I cancelled the trade in. Rather than backing out the credit, Amazon has stated they will be charging me. Keep in mind the entire credit amount was still on my account at the time.

I also realized that the book I ordered is an international edition. I’ll attempt to sell it to Amazon, but they will probably reject it on these grounds and then I will be attempting to sell it myself. This has the benefit of providing cash rather than an Amazon credit, but will take longer. I’m also not sure Amazon will FBA (Fullfillment By Amazon) international or instructor edition books.

Update:
I checked the USPS tracking number again and it’s been accepted by USPS. I wrote a letter to the seller about how frustrating this has been. No response yet.
