Mecca Coffee is currently doing a free shipping deal for all living in the NSW area with no minimum spend. They have a range of coffee blends, pods and gear for making coffee (filters, drippers, aeropress kit etc). Orders for Sydney metro should arrive in 1-2 days, with a tracking number provided. I haven't been able to find info about when this free shipping deal started and when it might end - apologies for that. The deal itself will pop up once you add an item to your bag.
Update: I did some testing with some orders (VIC and QLD) and I believe this deal extends nationwide.
