The additional 10% off the current 20% off Avo Seconds box is for a subscription which you can cancel after your order
Seconds means "good quality avos with either marks or slight imperfections which means we can't include them in our regular boxes".
In my experience the seconds is what the supermarket ones end up like once everyone's had a wee fondle.

Seems pretty good at $4.302 a kilo without shipping, tho Countdown with its odd bunch can go down to $4 a kilo currently at $5 in various stores. But countdown doesn't always have odd bunches so defo a good alternative
