Seems like Modern Man are having a 20% off storewide sale for Black Friday. If you want to get shaving creams, razors etc for a much lower price than buying it from an Australian store, you can shop here. Shipping is free over AUD 110 or $5.50 for orders under $110. You can also switch the currency in the top right hand of the page and pay in GBP as in some cases, some products end up cheaper when paying in pounds compared to dollars.
Eg. -Proraso Wood and Spice 100ml is $6.36 whereas it's regularly around $20 from local stores.
-Cella almond shaving cream in a bowl is cheaper buying in GBP compared to buying in AUD.
Tracked shipping costs extra and shipping will take a while. I have ordered from them before using untracked shipping and it took about three weeks for my order to arrive in Sydney. Also, they have a loyalty program where if you spend over a certain amount, you get 10% off your next order. If you make another order after that, you get 15% off future orders. This discount stacks on top of the 20% off storewide sale.
