I just spotted this on Amazon and thought it was a great deal. N.B. That this is the angled version, designed to stop you smashing your knuckles on stuff!
I will admit that £45 for "an over engineered adjustable spanner" does seem a bit steep, but they really are great to use. I use my current non-angled 180mm set for loads of tasks.
Dispatched and sold by Amazon UK. Free delivery even for non-Prime members, as it is over the £20 threshold. Next best price I can find is around £65.
You can usually pick up the non-angled version (86 03 250) for around £50 on Ebay/Amazon, but the angled version (86 43 250) always costs a lot more.
