The Redex stuff everywhere sells comes with a spout if bought in 10l quantities. This is available for around £25 from scrwfix/toolstation, or the last lot I bought was £9.50 at Asda

The price of Adblue has shot up over the last couple of years. I remember when Euro Car Parts sold 2x10 litres of GreenChem Adblue for £16. Last one I bought (Redex) cost more than that for 10 litres.
And it doesn't help that every tom, dick and harry now needs it, increasing pressures on supply. I think ShitFix/Toolstation as just under £25 for 10l from memory (these 2 are convenient for me, as they are both in Brakkers), but as said, occasional bargains to be had, like when I was in Asda MK last month
