Discover WILL be price matching Black Friday prices including door busters. Same procedure as always holds:
1) purchase the product now (make sure model number is identical)
2) after BF, call up Discover price protection line (1-800-DISCOVER = 1-800-347-2683) to file a claim
3) They will mail you paperwork. Fill out the form and send it back along with your receipt + ad/sales receipt showing the BF price.
4) Get a price match check in a few weeks.
