Saw this hack on mydealz and thought I'd give it a go - it works!
Steps -
1. Add a product to the cart but don't pay yet.
2. Add a Russian address (I used the Moscow McDonald's) to the shipping address at the time of payment. Change your delivery address to this one.
2. Apply the ALI promo code plus any other coupons you have.
3. Use the method of payment "other methods" but do not pay and have the product in the section pending payment. Cancel the order with the option to change the shipping address (done via My Orders screen).
4. Add the same product to the cart again.
5. Apply the ALI promo code with your Australian address.
6. Pay normally.
Somehow I just bought $15.81 aud worth of stuff and $7.17 aud discount applied automatically….no idea what it’s for and don’t see any coupons applied and didn’t have to do the Russian address routine
