HDMI Cord Differences

I got an Apple TV for Christmas and I need to purchase an HDMI cord. I remember when I bought my TV a couple of months ago from Best Buy, the prices ranged anywhere from $10-$120 per cord. I asked the salesperson what the differences were and he didn't say much other than recommending one that was $60~.

Is this all a scam? Am I going to be just fine going with the $6 HDMI cord that's on sale from Amazon? I've done a few Google searches but didn't come up with much other than a few articles from years ago. The general consensus was that they didn't matter much between price ranges but I didn't know if that was still true with the new technology that's on the market today.
