JB had this laptop for $260 previously, https://www.ozbargain.com.au/node/193622
Now HN has it for $278 after $39 ACER cash back, link for CB: http://ec3.acer.com.au/AcerCashBack/ACA/Projects/CashBack/Lo…
You can get $25 Voucher from HN: https://www.ozbargain.com.au/node/194595
Combined with the $50 AEMX rebate, the final cost would be $203.
NOTE: to take advantage of the AMEX promotion, you need to spend over $300 on card (if you use the $25 Voucher from HN), I added the Trend Micro Mobile Security, which is free after CB, link: https://www.ozbargain.com.au/node/197230
Too bad, the laptop has only 2GB RAM. Otherwise, it is a better deal than what TGG is offering at $239(after the cashback $25 from MS, $203).
