Hmm, yeah, I still don't love using floats here.  We're begging to screw something up...also, this is applied to ALL submit buttons.  Let's limit it in scope.  Something like this, which I still don't love, but is better:
```
#content #checkout_page_container #change_country input[type="submit"] {
     display: block;
     margin-top: 5px;
}
```
