Buy one or not! Looks too good to miss!
Don't discuss other things that the boxfull could make!! They really don't want to know! though they can't be that stupid!

Too expensive! Draincleaner and KNO3 works out a fair bit cheaper. . .

Except that drain cleaner in the UK is a pH neutral mix of surfactants and enzymes 
unless you can suggest a UK supplier of Sulphuric drain cleaner.

That is FAR too expencive!
The drain cleaner i buy here (UK) is £5 for 1.5 litres or so. it is light yellow and viscous, i titrated it to be 96%
