I too, think postage on many items is absolutely outrageous. I for one have refused to buy somethig I really liked because of over the top postage. I also note that these same sellers will not reduce postage by much either so still no takers.
I have seen some items come back over and over again with still the same postage and no one was buying.
Sellers need to be a little more realistic with postage and realise people are after batgains.
