"Thomas Farms Boxes for everyone! Invite your family and friends to try Thomas Farms Kitchen and as a reward for your efforts you will receive $30 off your next meal subscription order when they order for the first time. They will also receive $69.90 off of their first meal plan order as well. The more you refer the more you save. From our family to your family."
I don't think you can get this amount of a discount without this referral code but happy to be proven wrong. If you have a referral code add it to the comments and get $30 off too; you don't need to use mine. The point is to let you know there's this deal. If you use the referral code that's great if not no loss.
Pretty sure this has expired: https://www.ozbargain.com.au/node/300385. Full disclosure I am associated with CompareMeals now but not with Thomas Farms Kitchen. I order from them once in a while and saw this deal and thought people might want to order. I've tried their food and their portions are larger than other meal kits (I think). They are local meat producers so I suppose they use their own stocks at low prices.

The cheapest meal plan is $69.90. So you get your first three meals for two people free. I guess you could cancel or pause after giving it a go.
