I’ve mentioned generic brands before with headache tablets – aspirin for example. In Australia they are branded (they have a name), but are considerably cheaper than better known tablets.
But you can find generic brands everywhere, in supermarkets especially.
You might think that generic brands are not as good as the real thing. Sometimes it’s true. But often they ARE the real thing. Try them out and see.
Make it a game to see if a generic version of an item is available.
Wine is a good one to try for. Cleanskins are sometimes real value and quality too. But you’ll have to taste them to find out. I return cleanskins, though, if they taste like vinegar. You’ll usually get your money back – you won’t if it’s a branded wine, unless the cork has really failed. But these days, corks are hard to find.
