I have never heard of HelloFresh before receiving this $30 code.
Browsed their website, seems reliable, the idea is good, and it's a co based in surry hills Sydney, shipping is free, except the cheapest box i could find was the veggie box for 3 meals and 2 people for $59. so thats comes down to $29, still.
I know not all ozbargainers would agree it's a good bargain, but I love to give new things a try, so it's a good bargain to me before committing to spending more $ on this kind of service.
(Edit: Terms &Condition - This voucher is only valid on a household's first box. only valid on classic and veggie boxes. Order online. When using this card you will be signed up to an ongoing weekly subscriptions)
I've used them a couple of times. Thought their stuff was good, but worked out a bit expensive for me. Not bad with the discount.
