If you're ready to get a head start on Black Friday shopping, Walmart is officially open for business. Although the retailer's main Black Friday event doesn't launch until November 25, there's plenty of juicy deals to shop in the meantime.

Need to set the scene with a good tidying up? There's a Shark Navigator upright vac for less than half price ($97, down from $199). Then pull on your toasty new memory foam slippers (now a ridonculous $14) while you get a soul-restoring, rib-sticking feast started with this Hamilton Beach slow cooker for just $40 (was $53).

Walmart announced Monday its plans for its second Black Friday sales event and for its Cyber Monday sales event. Here's what to know.
