What is the process of going through the Bunnings Drive Through Timber section? Do you just drive in, pick up what you need and drive through a checkout on the way out? Do you have to be a tradie? What else is in this mysterious section of Bunnings that not all venture into? What am I missing out on? I'm a bit embarrassed to ask having never done it before and the Bunnings website says nothing about it in the In Store Services section!
