This is part of one of there graduated promotions, so $50 off the first box, $30 off the next and then $10 off 2 additional additional box if you choose to continue.
You can cancel at any time so there is no obligation to continue beyond the first box.
Pretty sure its not targeted. Just recieved an email today and it says it is valid for 1 week.
Meet and veg box, 5 meals for 2 people works out at $69.68
