Over 1700 items up for sale on Nike.com (AU site). I regularly purchase from the Nike online store as they have a much bigger range than retail stores.
From what I can tell, these items are usually shipped from Netherlands, which takes about 3-5 business days from my experience. Returns are free (send to a local Australian address in S.A. via Aus Post). Free delivery with orders above AU$100. Just a note that you might want to use a no-international-fee credit card as some banks may consider the purchase as an international order even though it's listed in AUD.
Don't forget cash back from Cashrewards 5.6%.
Any fire proof ones?
