I have noticed there has been a delay in getting mail if it has to go through NSW,QLD, i cummunicate and let my buyers know the situation as atm im in QLD and delivering to NSW and Vic in particular , my items are arriving couple days over the average which rarely happens so too avoid bad feedback cause of it i thank them for buying the item and politely tell them because of the current bushfire situation your item may arrive couple days later then normal.
I am waiting on Large Envelopes from Sydney atm to put my items in, my estinate and its always been on time was by last Fri, i got a text that i may get it tomorrow ( Tues ), i need the envelopes as i have items to send out so some communication with your buyers will go along way with these fires around.
Take care and happy selling ๐
