Great money saver is the internet.
You can easily have about 5 different online shops open in your browser and compare prices.
Its like being in 5 shops at once. A good website for this is

www.OneShop.co.za

. They list only websites that pass certain requirements. So you know your shopping at a reliable stores.

Also visit online comparison shops, these websites list products from a whole lot of different shops. So when you search for a product on their website your given prices from a couple of different shops.
Good South African Comparison shops are:
www.jump.co.za
www.bluesting.co.za

These websites above don't always have every online shop in their databases. So don't stop their, search on www.Google.co.za for your products name, hunt for cheaper prices.

People, like myself are still very sceptic about buying online. Especially big expensive items

Its a great tool to get the market related price for a product and then go purchase the item in store. Then I know what price to look out for.
