I was in St Helens branch of Currys today and decided to get the 4 pack of micro-trunking that is suitable for speakers, phone wire and other small wires. It was priced at £29.99, but reduced to £9.97. When I took it to the till, it scanned at £6.49
On their website, they have some reduced to £7.32
I know the £29.99 price is a joke and a while ago, I managed to get some for 47p, but for what it is, it seems like a very good deal to me.
The link takes you to similar stuff, but not all of the range is listed. They had plenty of stock too in store
