Chemist Warehouse have a limited time promotion for free same day delivery on online purchases, with no minimum spend.
Ordered a $15 item at 3pm and i already have a notification that the driver is on the way (3:45pm delivery estimate, in Melbourne).
Handy for those WFH and can't be bothered making a trip.
*Does not apply to medicines (I assume prescriptions) and not available in all areas.
Note: I tried a few different items and the deal does not apply to some that are low stock or not available online.
Edit: Got my order delivered just now. Took a little under 35mins from when I placed the order.
