from Walmart's facebook:
Walmart Hi Keri- If you have an item on Layaway and would like to receive the reduced price during our Black Friday sale the item(s) would need to be deleted from the Layaway account and added back to receive the event price (or price matched whichever is lower). Keep in mind layaway will be closed until 9am on Friday. Layaway items in Event 3 that begins at 5am on Black Friday 11/23/12 will be the only items eligible and the adjustment must be made in our Layaway department on 11/23/12.

Hmm so it sounds like it may work for the time period when the item is on sale by how I am reading that.
