While DSE have come out with their 10% off Apple pricing (and it seems every other reseller does every other week) it seems that TGG missed the memo that Apple was going to jack up prices on Thursday last week. Hence their advertised pricing is 10% off the old prices.
DSE Swanston St have put up their 10% off pricing yesterday, and it is 10% off the new Apple pricing ($1399 for MBAir 11") whereas TGG has the old pricing ($1250 for MBAir 11").
Officeworks are actively price matching TGG, and therefore another 5% off, so long as the OW store has them in stock. I picked up my MB Air 11" for $1068 after the price match, which is better than the DSE 10% (plus any possible Coles Gift card 10%).
It expires tomorrow night though, so go quickly if you are intending on buying a Mac now.
Dick Smiths prices are unchanged, according to their website. They are higher than yesterday's prices because they had their 10% off sale yesterday, but they have yet to pass on Apples price increases.
If you had purchased from DS yesterday and used discounted cards (from Coles) then the final price would have worked out cheaper. If you had used Wish cards then it would have worked out the same.
Still, nothing beats the $799.20 + $50 eBay voucher from this previous deal https://www.ozbargain.com.au/node/204710
