BEST Pool Shops & Supplies in Cangai NSW 2460

I recently tried to get pool salt in Grafton and eventually found it here. Everywhere usually sells it for around $7 a bag but because of the heavy rain recently and no stock anywhere else this shop decided to take advantage and charge nearly $14. Absolutley disgraceful taking advantage of customers like that and will lose my custom forever. Can't do that in a small town.
