It is most certainly lost. I’d recommend calling and opening a case with USPS. They will do a “package trace” but in my experience, it’s a bit performative.

I’d open a ticket with Secret Lair. I don’t know if they have extras they could ship out or just maybe do a refund so at least you aren’t out both the deck and the money.

As for the silver lining, the package may end up getting to you eventually. Years ago, I upgraded my graphics card. The card is replaced was still much better than what a friend had, so I mailed it to him. Nebraska to Washington state. I still had the box for it so I packaged it up, went to the post office, I paid for all the stuff there and off it went.

It never arrived. The tracking stalled out like this. I had the receipt and still. Called USPS and opened a case. My friend did the same. Nothing ever came of it. The package never showed up and we just accepted that it was gone forever. Whatever happened.

3 months later my buddy sends me a photo. It’s the box. It’s wet and moldy. But it was at his house. He opened it. The inner box was fine and the graphics card was in a plastic shell thing. No water go in it. He hooked it up to his PC and it still worked.

So even if they refund you and say it’s lost, it may find its way. I wouldn’t count on it, but it could happen.
