Supposedly Kogan has already started shopping S10 orders now.
On the downside, you don't get the free Galaxy Buds with this offer. These are wireless headphones that retail for $249 - a pretty significant compromise for getting the phone early. (You do get a free Kogan SIM card with 20GB data and unlimited calls, though.)
This offer might be for you if you want to be a super early adopter before official Australian launch and don't care for the free buds. You'll save 100+ on this grey import
