I preordered at MKII upgrade kit last December. However, due to unavoidable circumstances, I had to ask them for a refund three days later. For some odd reason, on mid to late January, PS Audio had sent me a package of the upgrade kit. Since I know I requested for a refund and I did not know what to do with the package, I left it unopened. It took until late April or early May that PS Audio finally contacted me for the package I did not pay for. Fortunately, I left the package unopened so I did not need to go through extracting process. I asked for a prelabel and they had sent me an e-mail along with it. I was planning to leave it unopened for a year. I could've opened it earlier since it was clearly not my fault, but a part of me told me not to.
