I have always found Transair to be a very good outfit, have visited all the shops in my time and frequently order on-line..never had a problem, but crikey you do pay for it!!
Was in the TF shop recently with time on my hands so bought a book to keep me amused (Vipers in the Storm..brilliant read...I digress) paid £18.99 for it - went back to work, chatting to a colleague at work and he looked it up on amazon...£6...D'oh!!
