For the people who can't tolerate lactose very well, Lacteeze is finally on sale. Unfortunately not as cheap as previous posted deals though :(
Edit: Sadly can't order for click and collect. So either purchase in store or ask for price match at other pharmacies
Paid $25 or so a month at Woolies about a month ago, and while I did use it towards a rewards point shop haven't seen it this cheap in a while, so still definitely a decent price.
Also by far the best product on the market.
