Another £10 bonus event on quidco
£10 Quidco bonus when you spend £25.00 (excluding delivery) at Book People, The Book Depository, AbeBooks, WHSmith, Wordery or Waterstones.
A qualifying purchase requires the member to opt in and make a cashback earning purchase through the Quidco site, via the specified retailer pages, by 23:59pm on 12 December 2016.
edit: no VAT on books, so £25 is what you need to spend excluding delivery, thanks calmacuk
edit: according to t&cs £10 bonus will appear within 3 days of normal cashback being confirmed (initially it will just appear as tracked)
The £10 bonus will be automatically added to users' accounts 3 days after the purchase has been confirmed by the retailer.
