Good grief, £13.58 for just over 2kg of salt to chuck on your drive! The garden centre near me sell a 5kg bag for about £3. That means Q are charging £10 for two cardboard tubes that didn't look that easy to use. They're having a laugh, surely?
10Kg for £2-99 in Lidl
* Perhaps they come with good looking youths to help scatter the salt on the elderly persons drive/path for them!
And they had the cheek to say table salt doesn't work - well it always worked for me when i didn't have rock salt to put down and far cheaper than what they charge!
