NewEgg has launched a 72 hour pre-Black-Friday sale where they guarantee prices won’t be lower on Black Friday (or they will price-match them). However, it is not clear whether they are price-matching their own website or the whole internet. Some of the deals require promo codes, and for those to work, you must be signed up to the NewEgg e-mail e-newsletters or be willing to sign-up for them. Of camera and photo interest:

+ Adobe Creative Cloud – Digital Membership [Prepaid 12 Month] for $380 with promo code
+ various hard disks
+ Expires Monday 11pm ET: 5% total order with promo code NAFBF14A at checkout
+ only one promo code will be applied per item per order (in other words, items with dedicated promo codes won’t be eligible to stack general purpose promo codes)
+ promo codes expire at 3am ET on 11/27/14 unless otherwise indicated over there

This sale ended: If you want to “test” their price-matching guarantee scheme, they offer Corel Paintshop Pro X7 for $40 with Promo code but it currently goes for $33 at Amazon.
