A fantastic deal on both the 55" B6 Flat and 55" C6 Curved 4K Dolby Vision/HDR OLEDs at the Good Guys Ebay store with the 20% promotion. Free pick up is available from the Good Guys or postage is around $35.44.
LG OLED55B6T $3196
LG OLED55C6T $3196
It would seem the Good Guys don't have access to the E6T models.
Don't forget if you purchase via CashRewards you can possibly save another $39.99, or via the Qantas Mall and score 3196 Qantas points, or via the Virgin Australia Shopping portal and score 6392 Virgin Points.
The E6 has an integrated sound bar - so if you have no interest in that (or run your sound through an amp etc) then the B6 may be a better choice anyway.
