Buying necessities on the cheap -- Hervey Bay QLD

Hello,

I'm looking for ideas on how to cut back on spending. I don't really buy luxuries so cutting back on luxuries is no help to me, buying necessities on the cheap should be beneficial, I'm thinking buying soap, shampoo, cleaning goods etc in bulk online would lower costs, I've done a quick search but would love suggestions on places to shop if other people are doing this too. I price match where I can and always use Chemist Warehouse for cheaper medications and bits and pieces.

Basically, I would like to know what necessities you buy on the cheap and where you buy them. I live in Hervey Bay QLD, so if anyone local has any suggestions of local shops that would be awesome too.

Cheers
