£6.29p Plus Free Delivery - Kingston 16GB Data Traveler Champagne SE9 USB 2.0 Flash Drive - Amazon UK (Bentham Ltd)
A few pence shaved off since the last cheap deal but I still thought it prudent to post it still, as every little helps ;) - hope it's of some help to you. :)
EDIT: According to a previous deal post it should come with a five year replacement warranty - the note reg. that can be found via the following link.
EDIT 2: Link to the most recent previous deal is listed below in case anybody needs it for reference purposes.
