Anyone received their invoice for the IW New Year's Lucky Pack?

I reserved a  New Year's Lucky Pack with Innocent World the day they went up on the site. I received an email from them a day or two later, stating about the price error and to see if I wanted to keep my reservation. When I responded to them that I was fine with the new price and wanted to go ahead on reserving the set, they told me that they won't start sending the invoices out until sometime around the 8th of December. Well it is now the 14th and I have not heard anything from them. I know they are busy right now due to the holiday sales and Lucky Packs, so I am wondering if I should email them or just wait it out a little longer.

So, for those of you who ordered a New Year's Lucky Pack, have you received your invoices?
