Price drops for the Airpods and Apple Watch 6 (GPS, 40mm), stack with $15 discount codes SPRING15 or SEPT15 (Edit: Code SEPT15 courtesy of irarelycomment)
Codes could be targeted as they are not working for everyone. Make sure you are logged into your Mydeal account before entering discount code.
If you are not targeted, use code SHOPAPP in the MyDeal app for $10 off instead. That code should work for everyone.
Response from the store when I enquired about warranty:
This is a US model (MWP22ZA/A) with 1 year warranty to be availed at any Apple store everywhere.
I checked the model number. It is the same model sold by TGG and other Aust stores. From what I read previously online, Apple supports the item if it has the same model locally.
