I was in B and Q over the weekend and saw this deal instore but they had all sold out. The hob is now discontinued but available on the internet (i'm getting mine delivered on 18th November). It's probably not the best hob ever (in looks or performance) but for £40 delivered you can't complain. We have just moved house and thought this hob will do until we get a new kitchen fitted in a few years time.
Cheapest elsewhere (by doing a quick search) is around £100!
