Most of the early Black Friday sales this month have been starting off on the weekend, but Walmart is getting started with another "Amazing Electronics Event" tomorrow.
The big focus on Wednesday will be towards discounts on HDTVs and Blu-ray movies. Prices won't actually be posted until the morning. Until then, you can browse the current online-only specials.
All sale prices mentioned here (and more to be seen) go into effect on Wednesday, November 17. Note the fine print: "Prices may vary in HI, OK and WI. Quantities are limited. No rainchecks. Offer not valid in Puerto Rico."
Don't forget that Walmart is also offering up free shipping on all electronics purchases until December 20.
