Hi,
I hope you understand that the sellers are liable for lost items. I ship through Australia Post and it can take up to 21days (from the date of postage to the day it arrives) for items to arrive sent from one place to Australia to another. This may sound ridiculous and I would agree but there has been plenty of times items have taken this long to get to customers. This doesn’t happen all the time but happens often enough; sellers do not have any control over Auspost delivery times. Items also on the odd occasion go missing (for which Auspost basically take no responsibility for) Most good sellers will replace these items at their own cost, because at the end of the day eBay holds them responsible for the missing item and most are trying to offer great customer service.
Cheers Chris
