It looks like you have to spend $10 to get the free polish....this is from their Facebook page....We cancelled all orders that were placed that did not comply with the terms of the promotion (Orders that just had a free america and nothing else). You can reuse the code to place a new order.
Oh no! Mine went through early this am, without another purchase. It sounded a little too good to be true. So now I'll just wait for my order to be cancelled
ETA: I checked my email but haven't received any cancellation to my order. So unless I get an email later cancelling the order, I am guessing its going through.
You won't be receiving cancellation notices in your email. Which in my opinion is bad business. Free or not... and apparently in the early hours they didn't specify that it had to be for an order of $10. :/
