Best Buy (15 days)
From the Best Buy website, "If we lower our price during the return and exchange period (15 days), we will match our lower price, upon request."
Just keep your receipt and head back to the store to get the lower price.
For online purchases, call them at 1-888-BEST BUY (1-888-237-8289) and request your price adjustment.
Will it Work on Black Friday: No.
