I'm so sick of waiting in line for models I don't want and am thinking of purchasing from the apple store online. I have some questions though.. 1. When you order online, does your card get charged right away or as soon as it gets shipped? 2. I know there is a 4-5 week wait, are others waiting for this and is there a possibility it will be quicker? 3. I want the AT&T model, so this will probably take the longest amount correct? 4. In the case where I want to return the iPad when it arrives, would any Apple Store take it and refund me? Thank you!
