On clearance, $8.99 a box but you need to
spend at least $10 buy 2 for free delivery. My Mum was excited for the pink colour :)
I find the quality of these to be quite good, a noticeable and step above the usual $5/box ones. Being more expensive though it can only be expected.
Edit: I have no idea what the rules are for free delivery, it might be for 2 or more items? There also appears to be a surcharge for orders <$10.
