I was buying a domain name at Network Solutions last week and between the choosing and the paying, there's a screen where they try to sell you a number of options. This is, of course, known as "upselling." It makes sense and it's not a problem if the options are relevant and the approach isn't pushy. And as long as you don't use the word "upsell" when you're talking to me. And the URL, whether they know it or not, is talking to me.
