I love a sale! I bought 3, 2 of Adrain Tchiakovsky's Empire of Black and Gold series and the first in The Painted Man series by Peter Brett.
As ChristopherTD says:
Fortunately (for me) their website is awkward to navigate so I can't find anything more that I want just now...
...and how! I emailed their Customer Service just before Christmas after I'd been trying to find a particular book:
I've just tried to find a particular ebook on your website. This is not the first time I've had problems finding anything on your site, so thought I'd share the experience on this occasion!
I wanted to see if you had 'Devil's Brood' by Sharon Kay PENMAN.
I first seached on Devil's Brood and specified 'Title'. This produced 168 hits.
Top of this list was:
Inflectional Morphology
by Gregory T. Stump
No.2 was :
The Brooding Frenchman's Proposal
by Rebecca Winters
....followed by 17 pages of hits, none of which was 'Devil's Brood' [trust me, I looked through them all].
I then searched on 'Sharon Kay Penman' and specified 'Creator'. This produced 500 hits, including such delights as :
Allergy and Allergic Diseases
by A. Barry Kay
Bargaining with the Billionaire
by Robyn Donald
Colloquial Russian 2
The Next Step in Language Learning
by Svetlana Le Fleming
and my personal favourite:
Celiac Disease
A Guide to Living with Gluten Intolerance
by Sylvia Llewelyn Bower
The Devil's Brood, by Sharon Kay Penman may well have been amongst the 500 but, frankly, I lost the will to live after scrolling through the first 10 pages. So WH Smith lost a sale.....again!
I suppose I was a bit flippant but their search engine is torture! Needless to say, their reply was so bland it seemed to be computer generated.

Sigh.
