Bought on ebay for £11.99 this is several errors in one; the card itself failing after a week or so of use and in buying it from Hong Kong, paying significantly more for the non-refundable postage charge than for the item thus making the returns policy prohibitive.

The faulty card is now listed on ebay.

UPDATE: It seems ebay.co.uk now shows the postage cost next to the price, which is quite sensible. I like to think my little bit of pressure helped there. It doesn't stop the "required postal insurance" cost obfuscation but it does make unreasonable item cost vs postage cost ratios more visible. Remember: you can't get a refund on the postage cost!
