I use their Wish List service to collate my book lists. Sometimes, people are nice enough to purchase texts for me.
However, due to the prevalence of camwhores and privacy advocate dickfaces, I'm forced to specify a delivery address completely separate from my account's primary delivery address. I know this. I thought I updated this. However, ho-ho-fucking-ho, thanks for letting me know a week later I didn't find the correct voodoo link.
Gosh, it sure would be nice if that could be done through my account settings page.
