Ok so decided to go down this route to save killing myself but where do you buy this weedkiller.

Was looking at their website and would like to get this one:

Tesco, Wilkinsons, garden centres.  Roundup is everywhere Foxy.  Green and yellow box or bottle.  I'm not overly keen on the stuff myself, but when I want to get rid of weeds on the drive, I used straight glyphosate, which I got at a local horticultural place in Spalding.

It still didn't work, but is stronger than roundup.  I'm strying salt next on the drive, thanks to advice from Munty!!!

... but if you have an old tin of creosote ... which of course you won't because it's illegal, and not PC ... but a drop of that on any stubborn weed will work quicker than anything else you can beg, borrow or steal.

And it's horrible stuff to boot, but just if you happen to have a tin!

Don't think you will get that exact one foxy it's got diquat in it as well as glyphosate, I assume its an American website.
Best bet is like grannieannie says wilko's B&Q etc, buy the concentrate rather than the ready made up stuff, it works out a lot cheaper.

Much cheaper to buy glyphosate than Roundup.  It's exactly the same, just not a brand name.
