Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
That's not good. And it certainly doesn't help customer relations.
You should without a doubt be able to cancel any item that has not shipped. If they ship it to you anyway, after you indicated you wanted to cancel the order, you should NOT be liable for any charges incured, if the item is returned.
It's such a waste of time to ship an unwanted item only to have to go through the hassle of returning it.
