In general, not aimed at you Mrk, but to everyone: Please can you install a Greasemonkey / Violentmonkey script called "General URL Cleaner"? It shortens Amazon and eBay etc links to just what is necessary. So that the link I quoted above becomes https://www.amazon.co.uk/dp/B081KYHLWT .. it just looks tidier when linking on forum posts.
