This often happens to me, but instead of Euros it's USD, since I live in Canada. I think this occurs because you click on links posted here on EB, that link you to the Euro S@H pages. Your computer remembers that Euro selection and takes you automatically to the Euro S@H. All you have to do is select USD again and look around on the site so your computer remembers that.
(All this coming from someone that knows relatively nothing about computers )
