I've been using this without any issue (or so I thought) for several years until a customer just contacted me and reported some weirdness.

If I am logged in as a customer, add something to the cart, then modify my profile the mini-cart will show a certain amount for shipping once I click 'submit' on the profile page. When you go to the checkout it shows a different, typically higher shipping amount.

Here is my minicart.tpl code if that helps:
