How do I buy phones online?

[Ferrari353]

Okay so I found an amazing price for the HTC Inspire 4G online, but it's weird to buy it, and I'm not sure what to do...Here's the site: HTC Inspire 4G - HTC - Car Toys
I'm in a family plan currently, so I try to upgrade my current line, and it's like making me pick a voice plan, so I switch to "family plans" and then it says I have to add another line...So what's the problem here and how do I fix it?

Print it out and take it to a store, ask them what they can do for you.

What if they say they can't offer me any discounts? Is there anything I can say then?
