Thought that I'll just chime in on this matter.
Off-topic first (funny, I know)... I'm surprised you have that saying over there! We have an exactly same saying here, that you don't check the teeth of a horse you got for free!
Now, back on the topic (sort of)...
I can't speak about everyone, but as far as I'm concerned. I'm not fretting, not even the slightest. I'm perfectly happy about receiving the tank with a single coil. It's great! It's free! If it comes with more than one coil? Wow, even better, I'd be even happier!

Anyway, what I am trying to say is that for some people, me included, it's the very first time they've won anything... up until now, the only thing I had won in a lottery/giveaway, was a flashlight, about 20 years ago. So... I'm genuinely excited! So excited, that I'll use every excuse there is, to discuss this wonderful giveaway, mod and tank. So, no fretting. I doubt anyone is fretting over how many coils will be included. They're just excited and want to talk about it...
Well, that's my opinion anyway.
Also, I'm double excited today. I got two notices prom post office today (over here, you don't get delivery to your door, if it's anything larger than a newspaper)! My first EVER vapemail!!! Wheee.... judging by the tracking numbers on the notices, my Koopor Mini has arrived from Cigabuy (order placed on 21/08/2015) and my Nitecore D2 from AliExpress (order placed on 23/08/2015). Somewhat impressed, how fast they arrived from China!
Anyway... sorry for the long post!
Just brimming with joy!
