One of the most annoying is with Amazon - changing your home, or one-click address does not change where your wish lists send things to, I was just reminded. And it took me multiple tries looking at the wishlist pages for me and Rosie to find the "List Actions" menu and select "Update List Profile"
Anyhoo. My birthday is coming up the first week of December, and Christmas is coming up. So I have now updated our wish lists so that they will send things to our current residence rather than the last one.
One thing at a time.
