online ordering question

when i order online, and then pressed the browser back button, does it order again?
Answer #1
Some sites say dont hit back button but I have many times and have not once been charged twice so I think you will be safe.
Answer #2
Yep your transaction will be processed again! Mostely an issue with Credit Cards.
Answer #3
Best thing is to check your online bank statment. Once you click go, they will post it on your account at that moment. Well, in most cases. Long story short, do not hit back or F5 (reload).
