I want to buy a used card, how can I make sure I am not being ripped off?

Do your research! Look at the prices of cards online, read reviews, and ask around to find the average price of the card you are looking at. When you've decided on the card, make sure the seller is trustworthy and reputable by confirming that they are legitimate.
