Same with certain home improvement companies that hope once you're on the line, they can close the sale there and then.
I swear they must make all their money off people who don't want to think about what the job involves, and just hand over a chequebook.

The water softener from Costco is £500, the one from ScrewFix is £400, but I'm curious how much the one from NameBrand is.
NameBrand website "Well, it can vary a lot depending on how complicated..."
Forum posts: "£2k including fitting and a year's salt, £1500 for the unit"
(Which isn't an insane price to just have it sorted, I just hate the bollocks excuses when everyone magically still comes out around £2k)

The physical staircase will cost me about £1000, then a few days of skilled labour for someone to fit.
I wonder how much one of those "we'll just handle it" companies in the back of the sunday supplement could do it for...Oh, that's 15 times the price, wonderful.
