Why do some of you do this?

Aquarius

U post promo codes
Then when someone uses it they tell you which one try used.

I'm just wondering howcome ppl say which promo code they used. Do u have to manually deactivate them? Afaik they deactivate themselves. I could be wrong.

Once used they are dead. So it helps the next person taking one to know which ones won't work anymore.

SlickZero

So they know if one got used or not and they don't give it away to someone else.
