Look at it another way Ted. The spring on it's own is around £10, then you've got postage etc IF they would send it to the UK, that's most likely £10 as well. So you'd be willing to pay £20 for a spring (also second hand) but not £24 for a spring and pedal, as I said you can sell the pedal on, tidy it up, get it rechromed and it will fetch enough to pay for itself and the spring.
