Amazon buyer scammers

Hello, I sell many types of gift cards, from any store without problems, but I see that there are many buyers from Amazon scammers, is it only me or is it in general? Note: I send all my endorsements to gameflip support and in the end the buyer clears the dispute in a friendly way, or gameflip goes in my favor. But the truth is a stressful thing to sell Amazon thinking that at any moment you will be scammed.
