And this is the thing. Many people receive better after sales service from faceless online sellers than high street shops. The last time I used a shop, I was enquiring about buying a sensor cleaning kit. The slimy assistant in the busy shop shouted across to a colleague something like “Hey Steve, this one wants to buy a sensor cleaning kit!” And they both laughed.
The shop went quiet, I gave him a Paddington stare, and I walked out. 2005 ish.
Wex in Norwich are good, very good. If you need almost anything urgently, they can help.
