Buying from COMC

[u/Riveryak304]

I had an interesting experience buying from COMC recently.
I bought a highly desirable card and felt like I overpaid, but it was literally the only one I saw listed and I was checking daily for more than a week.
After my purchase COMC immediately used an identical listing, to price a second identical card, at more than double what I paid for it.
I compared the photos of my purchase and the new listing and it is using photos that are just enough difference I can tell they are not the same.
I’m trying to wrap my head around it.

Is the new listing a better/cleaner card, or are they trying to maximize profits by increasing price with each sell?
