Mine haven't changed much - but I don't have a high turnover, just happy with what I do.  

I have been researching my local area  (regional Victoria) "Buy Swap Sell" sites on Facebook, and after a quick search I found approx 6 sites, which have many members and items for sale.  Most are "pick ups" & available straight away.

I am sure this must have some impact on purchasing & paying postage type sales.
