The above listing embodies a type of fraud which (so I've heard) is often practised on eBay -- charge an apparently reasonable price for an item, which is given in large type up front, but also charge an exorbitant "shipping" fee in the small print.
So you buy this one small choc bar, thinking that you've paid the advertised price of £2.70, only to find when it's delivered that you have actually been charged £11.66.
(I don't see how a shipping cost of £9 for one small item from Austria to Britain is realistic; I have, several times, had much heavier and bulkier items sent all the way from Hong Kong, and the shipping hasn't cost nearly as much.)
The worst part of this is, Amazon aren't allowing reviews pointing out that this is a rip-off (they have rejected at least three in the past 24 hours), so they are participating in the fraud.
