Seller is in Hong Kong, so I wouldn't be returning without postage compensation upfront. If the cost of returning is more than the item is worth you could also argue that aspect.

The seller also seems to have issues with the eBay MBG - http://community.ebay.com.au/t5/Selling/eBay-case-8-days-time-limit-is-very-stupid/m-p/2035665#U2035...
