Online shoe retailer Zappos is apparently expanding its operations. If you browse the store’s electronics and computers categories, you’ll find a decent array of cheap subnotebooks like the Asus Eee PC and HP Mini-Note as well as some pricier, more traditional laptop computers.

As bloggers Dave Zatz and Kevin Tofel point out, Zappos does appear to be charging a few bucks more than other online retailers — but just a few bucks, like maybe $4 or so on most models.

And what does your extra $4 get you? Free shipping both ways. Zappos is known for letting customers order shoes, try them on, and send them back for free if they don’t fit. Now you can do the same with computers and other goods. Zappos is also renowned for having excellent customer service. But I can’t help but wonder if the customer service agents will be as well equipped to handle computer questions as they are shoe questions.
