The price issue beats me. I took the gamble and ordered 2 off ebay:
eBay My World - au-bestdeals
Two for A$2.99 and I could not be happier with the quality. Came with covers on both the front and rear faces (with little peel-off-tabs) + a cleaning cloth. The sizing was good and my 9800 works well with one on. It is very difficult to tell that a protector is in place.
