Was in one of my local Home Bargains this morning, we have 3 in Shrewsbury, and saw this Loctite Extreme tape in there. £1.99 for a roll of 30m and 99p for a 10m roll. They only had 30m in silver and 10m in black at this particular store but will have a look when I am in the others to see what they have. I bought a roll of each even though I don't need it, but it will come in useful at some point. It's £6 in Wickes (30m) so could be a bargain!
