Bought some items, postage $2 per item. A week later the postage went up to $20 per item. When I questioned the increase, I was informed it was due to Australia Post increased charges. Hmmm a 1000% increase. Now that’s what I call inflation.
Is it possible to complete a search for a specific item, rather than trying to search a category which may have 1000’s of items, when I have clicked on “Sellers Other Items”?
