You all continue to convolute two separate issues. We should not be discussing a mandatory return/refund period...that should be left to each individual seller in his/her individual sales threads. If I want to start a sales thread with an "as-is no return" policy, I should be free to do so, and you should be free to not buy the books in that thread if you don't like it.
What we need to stay focused on is the PL statute of limitations discussion...i.e., how long does someone have to initiate a PL claim on a failed transaction. That's a different question, and (I thought) that's the issue that's on the table.
Agreed. The simplest way I can think about it is this. Someone wants to nominate someone for the PL.
First question: Did the transaction happen within a year?
If yes, then carry on as usual.
If no, then sorry, the time frame for nominating to the PL has expired.
