Affiliate disclosure
How clearly labelled affiliate links support The Ludwig Casebook.
Live affiliate programme
Booking.com via CJ is the site’s only active affiliate programme. Clearly labelled accommodation links may earn a commission when a reader makes a qualifying booking.
Some pages also link to retailers and tour operators without any commission; we will update this page when that changes.
Every such link is labelled “Ad · affiliate link” and uses sponsored-link markup. If a reader follows one and makes a qualifying purchase, Does Your Duck Quack? may receive a commission. The price paid by the reader is set by the retailer.
Editorial independence
Affiliate links do not influence programme facts, reviews, evidence records, cast pages or production registers. They are kept out of evidence, cast and production records. A commercial relationship is not an endorsement by the BBC, Big Talk Studios, ITV Studios, the cast or any rights-holder.
Check before booking or buying
Availability, prices, cancellation terms, access arrangements and retailer stock can change. Check the supplier’s current terms before purchase.
Accommodation links
Booking.com accommodation searches use the operator’s CJ affiliate link and are marked Ad · affiliate link. They carry sponsored and nofollow attributes. A qualifying booking may earn a commission. Hotel choices and programme facts remain editorial decisions.
