Credit cards are at the ready as online shopping bonanza Click Frenzy prepares to kick into action.

Shoppers across Australia are counting down the hours until the annual online mega-sale event begins at 7pm on Tuesday.

The website offers thousands of incredible deals from premium retail brands with up to 90 per cent off – for one intense 24-hour period.

• Wild boar strolls into Hong Kong clothing shop
• Buying golf gear online: how to do it properly
• How to buy a winter coat on your lunch break

There’s clothing and baby goods, homewares, light fittings, jewellery, camping and hiking gear, alcohol and more.

Shoppers can search the Click Frenzy website for deals by category, brand, product name, item or just browse the range.

Beacon Lighting is offering 40 per cent off your second light purchase, Bookworld has up to 60 per cent off the full price of every book and Mr Shirts is offering any four luxury shirts for $199 – a whopping saving of $400.

Despite a stuttered launch in 2012, when the site crashed after being unable to handle the volumes of traffic, shoppers continue to come back for a bargain.

If you’re a Click Frenzy subscriber, you can get early access to exclusive offers plus an opportunity to win cash prizes up to $3000.
