I haven't changed my maiden name yet, so the bank account still shows Williamson. Which means that my bank card won't work if I put the wrong billing/shipping address. We ordered our sewing machine on Amazon and put the right last name, but not the shipping address. So, the sewing machine went to my parents.
No fear, I'm picking it up in the morning from my mom's work. Amazon also did this with some dvds I ordered. Not a loss, just inconvenient.
