R 25/ZR headlight bulbs
I recently had to replace my headlight bulb ( dipped beam) I called in to the local motor factors for the correct bulb. I was charged £8.99 for the correct bulb (ring manufacturer) incidently Halfords charge about the same. I was browsing around my local Wilkinsons store a couple of days later and to my horror saw exactly - yes exactly the same bulb for sale for £3.99 and they do most of the other bulbs including halogens at very reasonable prices.
