Potential scam?

New post with pictures.

I sent an offer to a seller on an item and they accepted. But directly after I bought the item, the item was then listed again for the initial price. I asked the seller and she said she has multiple and doesn’t like to take new photos and not to worry. Well I was looking at who the seller follows and it follows one person selling the EXACT listings as this person. Screenshots are the seller I bought from and the their items vs the other sellers items. Doesn’t mercari normally side with buyers if something isn’t right? Screenshot showing their rating on my seller.

Is this normal??
