Recently I asked several suppliers for a few parts.
Among them was Cornucopia in Germany.
It took them a few days before the answer came .
In the meantime I had found the parts with a local supplier.
I could have chosen not to react on Cornucopia's offer (which often happens to me after sending a estimate),
but I thought it polite to let them know that I had found the wanted parts.
The reaction from Cornucopia : Great Stuff Vincent, You know how much time it takes Will charge you double on any thing you want in the future !
