Does SY charge your card when you order or when they ship?
I am trying to get things in order for Monday <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
When they get ready to ship in my experience. So it should be a variable time after you place the order. I do not know if they check to see if you have sufficient credit available when you place the order or not. Some sites check to see if you have the credit, even if they do not immediately charge you.
This offer requires them to manually check that you are a forum member in good standing, so I would think nothing happens until the knife is ready.
