Only available on 'Christmas Club Night' which is the 9th of December. Starts at 4pm.
As part of the Christmas Club Night, SCA are giving away a free 2016 calendar with any purchase. According to the email received, Christmas Club Night is happening at all stores.
The calendar itself features various cars as shown here. With a quick search I found this reflective number tag to be the cheapest item, effectively making the calendar 10 cents (if you can find stock that is). No more information has been revealed other than there is a limited amount of stock, so be quick!
Anything else free? BBQ perhaps?
