You can get great bulk deals on fresh and frozen meat at Super Butcher. There is plenty to choose from including meat, chicken and seafood. They offer 'buy one get one free' specials and much, much more. They do have an online shop but you get the best specials by going in person. The actual shop is in a huge (very) cool room and they cut your meat to your liking onsite once you have made your choices. Be sure to take a jacket so you can shop in comfort!
They also have a weekly email service with the latest specials that you can sign up for. The prices are a little better than WW or Coles but the quality is much much better. Some of the specials are awesome.
