Who's Cheaper? Woolworths, Pharmacies and Chemist Warehouse

Since the birth of our daughter, I have had to acquaint myself with the world of chemists and pharmacies and quickly realised how they manage to survive without me all these years. In Perth, I found out that there are some things massively marked up in my local Soul Pattinson Pharmacy compared to Chemist Warehouse and Woolworths.

Baby Formula - NAN HA Gold 1 - Woolworths $22.40, BigW $24, Chemist Warehouse $24

Little Fess Nose Spray for blocked nose - Soul Pattinson $15.99, Chemist Warehouse $9.99

EDIT 2016: Added this one in 2016, got stung buying Nurofen for children so I need to let you know about this...

Nurofen for Children 200mL - Soul Pattinson $27, Chemist Warehouse $13
