The good news is that you will be pleasantly surprised (oops - ruining the surprise for you) that they are 11 bucks a pair, not a piece. So, when you recieve two pairs of them, you'll be happier
I got them yesterday and thought it was a mistake! I just saw this post so I am glad that they didn't make a mistake and give me two more by accident! I was going to contact them and see if I needed to send more money! They are so tiny sitting next to my 18650!
