At the top of the page right before you check out, there is a check box labeled "Check this box to default to these delivery and payment options in the future."

I'm pretty sure that clicking the "Click here to make this your 1-Click default address." link under the address you want as default (in your Amazon Address Book) will set it as default. If not, I also think it might automatically default to the last address you used to ship something.

I never use 1-click, always doing the old-fashioned "Add to cart" and "Checkout", so changing a 1-click option wasn't where I thought to look.

It's weird that during the check out process when you correct the address, the same option to make it the default there isn't present.

Yeah, I don't use 1-click either (I like to verify information before buying something), but somehow it always defaults to my home address, so I think that may be how I did it. :)

For what it's worth: you can set default payment method/shipping address in 1 click settings. (Your Account > Manage Addresses and 1-Click Settings)

I think I've had that problem before too...couldn't figure it out quick enough and decided deleting everything but the address I wanted was the fastest and easiest way to fix the problem...even though I had to re-add one or two of those addresses later on.

yeah it's in your 1-click settings, I'm sure the setting definitely exists. you could try clicking "help" on their site, haha.

The default shipping address for Amazon Marketplace orders is the same as the default shipping address in your 1-Click settings. To update this information, follow these steps:

Click the Your Account link at the top of any page
Click the "Manage your address book" link in the Personal Information section of Your Account.
Look at the top of the next page to determine if 1-Click ordering is turned on. If it is not, click the "Turn 1-Click On" button.
A line reading "This is your current 1-Click default address" will appear next to your current 1-Click default address. If you wish to change your 1-Click default address to another existing address in your address book, scroll down to that address and click the link in the line which reads "Click here to make this your 1-Click default address." If you wish to add a new address, click the "Enter a New Address" button.
When you are finished, click the "Continue shopping" button near the top of the page. Future Amazon Marketplace orders will be shipped to this new address.

P.S: I do work for amazon, but I just searched for "default address" in help.

I've had this exact problem more than once, including having a PS3 bouncing all around the country. As mentioned before, the "1-click address" fixed it, but it dodn't make a lot of sense since I don't use 1-click.
