Earlier this week I bought 11 books from Asda: a few Dean Koontz, Jonathan and Faye Kellerman as well as a handful for my partner that I though she'd like.
They are obviously not new releases, but all seemed to be by famous authors and there were plenty of copies of each.
After a search, it seems to be the same sort of deal as this posted by Late at the same time 12 months ago:http://www.hotukdeals.com/deals/large-selection-of-books-1-each-asd/586522
The aisle was set up in the same way as the photo in the thread.
This was in the Kendal store, but I assume it is nationwide.
Apologies if this has been posted - a search couldn't find anything recent (although it's always a bit random!)
