OK here is the deal. You are going to visit Airsoft Sports page. You will then proceed to find the festive chicken on the right side of the screen. Then you will click the current day and enjoy the awesome discounted item that you will be linked to.
Today on the 7th of December you can get 60€ cheaper Polarstar Jack but what will the future bring no one knows but it will surely be awesome. So I do recommend visiting their site.
