I'm planning on buying the Dell U2410 and a quick google search gave me websites to buy it from where it's $50-$100 cheaper than direct from Dell. One of the better features of the monitor however is that you can swap it easily if there's a dead pixel. If I buy from one of these other retailers (say, Buy.com) can I still do that? And would I deal directly with Dell for such a potential issue? Otherwise, does anyone have any coupon codes that currently work on Dell.com? Thanks.
