Ask before buying

The good thing about all of those super electronic stores is they usually employ pretty knowledgeable people. So, when shopping for a computer system you might as well kill two birds with one stone. Ask questions not only about the system you're buying, but what broadband provider would work best with it. Ask about the benefits of using that type of broadband service. Depending on the store you might even get printed information that provider has supplied. Plus, some providers even have relationships with stores so you could get some sort of service discount as well.
