You appear to have Zero feedback/activity here and someone else seemingly "paid" through A'Gon's system for the item.
Yes, it's normal and fair.
Sorry for your loss, but hopefully you will learn from it.

seller etiquette
I have been reading here for a decade, first recent post under my newly found login.
I have contacted a seller about a subwoofer for a fair price. I asked if local pickup was an option. I got a response that it was. I wrote him that I would drive up, from 2 hours away, in 3 days. I told him I don't want to disturb him by plugging it in, I would just pay and pick it up, as I'd trust his word that it works. I was ok paying full price.
I then yesterday afternoon got an email that I needed to pay asap or he'd sell it to someone else as he got another offer. I didn't read the email until this morning when it had already been sold.
Is this normal? Fair? How could I have avoided it? Should have offered to pay in advance? Should he had been waiting for my response and payment for a little longer?
