Dell's Memorial Day deals are too good to be true. This weekend, if you order directly from Dell's website, you can save $400 on the new Dell XPS 15, plus $250 off the XPS 13 2-in-1 and $1,000 off LG's 4K NanoCell set.

But that's not all. Dell's Memorial Day is also marked down on everything from laptops, monitors, TVs, and desktops. If you're looking for the right category, or just know that discounts strike when the iron is hot, you can score hot devices at up to 50% off.

Also keep an eye out for Dell's promotional gift cards. If you shop during the Memorial Day event, you could earn up to $200 credit toward your next purchase.
