Ebook rip offs
There are 2 rip off with ebooks (nothing to do with the hardware or retailer)
1. The government charges VAT despite the green credentials of something that needs no trees to die and no diesel to distribute. Bonkers
2. Publishers like Penguin seem to be able to insist on a minimum price often higher than the paper version - banned on paper books - even though the books can't (yet) be loaned or given away or sold secondhand so are truly 1 buyer 1 reader thus increasing sales and the zero cost of printing (well they have to convert the file to a different format), warehousing, distribution and then the remaindering of unsold stock.
So write to your MP and ask why the government charges VAT on ebooks but not paper ones and why publishers can flout the ruling on the abolition of the Net Book Agreement.
