I have purchased two Dell  laptops from Amazon.  Can't beat the prices and having the long-term Dell factory warranty is huge.  But in both cases, it took me hours--HOURS--to update the software, drivers and other grunt work to make them ready to use.  The second laptop, purchased a few weeks ago, was essentially DOA.  I was ready to send it back, but later decided to take the time to fix it.  I'm sure these things sit on the shelf until they're purchased.  But, C'mon!  Both arrived with no wifi drivers installed.  First time, it took several calls to Dell to figure it out.  Second time, I knew the drill.  I guess the prices dictate some inconvenience.  Just be aware you might be in for some make-ready.
