AUSTRALIADAY
Oobi kids clothing are very bright and psychedelic and groovy! :)
25% off storewide with code, including their VIP Club membership ($29.95)
Postage is from $7.50 (but depends on how many things you buy and ultimately how heavy the parcel would weigh).
Free postage with purchase over $160, or $40/$50 (if you have VIP Club membership). I am unsure whether it's $40 or $50 minimum purchase for free delivery. I think it used to be $40 but they may be increasing this to $50. The website has different amounts on different pages.
I've purchased their VIP membership today, but the status of my "order" is awaiting fulfilment, so you might not be able to make a purchase with free delivery immediately or even the same day. I'm still waiting.
But otherwise, 25% off storewide - and I'm assuming it expires 26/1/2014 - which is Australia Day.
