The finest bargain ive ever encountered, was when competing in the Rhyader Round the Lakes 20 road race, back in 1992.
Running Bear, the outdoor adventure sports company, had around five hundred seconds Helly Hansen thermal tops and leggings for sale, all for a £5 a go.
I bought six of them, and on inspection, cannot find any flaw or manufacturing fault with them.
Once people knew what was going on, they were sold out incredibly quickly.
