Just spot this on Dell website. Works out to be 20% off. The ST2320L seems to be a decent general purpose monitor. And at this price, I think it is a pretty good deal, no?
edit 1:
there are others monitors on sales as well, so check out Dell website if you're after bigger ones. And it seems like the cash off is not stackable with other 15%, 10% coupon codes. Anyone knows of a code that would work on this one?

note comment from frickendevil below regarding his experience with a ST2420L
Here is a thorough review of this LCD monitor:

TLDR — reviewers don't seem to recommend this monitor. It might be good for office work though, but if you're after image quality or gaming you might want to invest in something better.
