I did it before the hype and found some trending items. Check the google adwords and the math added up. It worked, no record profits tho. Then big local sellers started undercutting me a lot. I assume they have some data mining trending processes running. Ad costs spiked and it wasn't profitable anymore. It was a fun try, but not worth it for me.
