Idk if I'm allowed to post this on here if not delete and let me know there is a company giving away a free coin every week this week is a 2014 ms70 silver panda here is the link if anyone is interested http://www.coinweek.com
So by giving away a $50 coin they capture the email of hundreds of people in which dealers can advertise their stuff to all the non-winners. Seems like cheap advertising...
I've entered every week and haven't got one email from them. Well one to confirm that its a real email otherwise the only time they email you is if you are the winner to contact you to claim your prize
Even if you don't enter their give-away, I would urge everybody to subscribe (so you get their email announcement every week) and read Coin Week. You will learn something every week - http://www.coinweek.com/
