If you're like me, hayfever has season has started. Found this deal on Chemist warehouse with $5 cashback.
Store currently has free shipping for orders over $20. Don't forget Cashrewards!
Mod: According to comments online orders are excluded from cashback, the cashback form requires a physical store location. It would be advisable to order in store or contact the promoter for further information.
Look for unbranded Fexofenadine at your local pharmacy, it's exactly the same thing but it's always much cheaper than this.
