With S&S according to my calculator, it works out to $2.965 a bottle
Also, Rexona Men Quantum Antiperspirant Deodorant Aerosol Spray, 250 ml $3.15 with S&S https://www.amazon.com.au/dp/B08T7HDCLC
Tip for those without Prime and your order is under $39
If you want free delivery and don't mind waiting, select the S&S option. It'll be delivered by the 25th of the month (the cut-off date to order ends sometime in the middle of the month) but it usually gets delivered several days early - at least in my experience. The beauty is that you can always cancel and add things to the order up and till they ship it out. Just remember to cancel the subscriptions after.
Please let me know in the comments if I made any mistakes
