Browsing bitmissing's deal here (Thanks) and came across this. 60% off the TX direct on its own. Great for me as i scored 25(!) lts of tech wash for £30ish a couple of years back and still working through it.
I just picked up 3lts of TX direct for £21.99 delivered, so good value.
Add Tech Wash 300ml @ £1.50 each if needed
