Buyer thinks they can turn a profit from an already weak selling card.

A 2016-17 Upper Deck SS-NS Signature Sensations Nick Shore trading card was listed on COMC for $3.99 this week, and a buyer was quick to flip that card for $13.99.

If that buyer did their research, they would have found out other copies of that card sold for an average price of $3.16 (excluding shipping and handing) on a competitors website.

To make matters worse, the autograph on that copy isn't smooth. They really jumped the gun with that purchase...

They have since lowered the price to $11.99, but considering autographed Nick Shore rookie cards starts at $2.25 on COMC as of this writing, I doubt they'll make a profit from that card.

Question: What's your worst flip experience on COMC?
