SAVVY Australian shoppers are gearing up for US mega sales as experts say online deals are still much cheaper overseas.

Thousands of Australians bought discounted goods during this week's Click Frenzy sale despite its initial technical failings, but savvier shoppers have been waiting for the sale it was modelled on - the US's Cyber Monday - to grab even bigger bargains.

Cyber Monday will follow the iconic shopping event 'Black Friday' which has just begun in the US.

Each year retailers hold massive sales the day after Thanksgiving in order to kick off the Christmas shopping season.

Major stores like Wal-Mart and Toys R Us have just opened (at 8pm Thanksgiving night EST, 12pm today AEDT) with special deals, hoping Americans will be willing to shop as soon as they finish their Thanksgiving dinners.

The Click Frenzy website had more than 20 million page views, and even though there were good deals to be found Australia's cheapest online prices still don't undercut overseas retailers.

Financial comparison website Mozo has compared the lowest prices on popular Christmas presents in Australian bricks and mortar, Australian online and international retailers.

In some cases the items are 46 per cent cheaper at international online stores, even with shipping costs.

The Nigella Bites recipe book costs $55.95 in Dymocks, $38.80 at doubleday.com.au and $33 from Amazon USA.

Marc Jacobs Daisy 100ml perfume, costs $120 at Myer, $116 at fragrancesandcosmetics.com.au, and $65 at Hong Kong-based online retailer cosmeparadise.com.

The calculations for international prices were made using the average currency conversion fee of 2.5 per cent of the purchase price, with the exchange rate from Mastercard.

Mozo director Kirsty Lamont said local retailers simply can't compete.

"The bricks and clicks gap is getting closer for local retailers, but when it comes to online, by far the best bargains are still found overseas," Ms Lamont said.

Ingrid Just, spokeswoman for consumer group Choice, said the hype around Click Frenzy has raised awareness of the US sale among shoppers.

"I don't think your regular person in the street would necessarily be aware of Cyber Monday," Ms Just said.

"I'm sure [the coverage] would have flagged it to people who are shoppers, particularly those who are happy to shop online."

Ms Just said shoppers could buy from participating Cyber Monday retailers that only ship to the US by using parcel forwarding services, but people should do their homework before purchase.

"Look at the terms and conditions around these forwarding services, and especially at this time of year, and check the length of time it will take getting from a to b."
