Thanks/credit to l005e for commenting on their experience on the previous S10e deal. Seems cheaper than the student deal online.
I went into the Samsung pop up store in Penrith. Standard S10e price is $799, AND I ASKED them to check. (Caps lock because at first they said no way!) Their store manager checked and yes, so long as I was willing to sit down for a 10 minute diagnostic on my S8. Result is an S10e for $599. No exchange required so I'll be selling my S8 shortly! Go for it!
2 year warranty, but single SIM Exynos as it's official Samsung stock.
