Are cyber monday deals posted in advance or do I have to wait til monday?

I don't buy much of anything online, I have to see it first before buying it.So, I'm not experienced with finding out where all the good cyber monday deals are and whether or not they are posted in advance so I need to know that.

Do the sales start at midnight (sunday night) in my time zone (Eastern Standard Time) and end at midnight? Perhaps a dumb question but I need confirmation on that.

I'm looking for: An internal desktop SATA hard drive o/a 250GB's or slightly smaller (no need for anything big), a good quality 16GB or 32GB SD-Card for taking 720p video on my Nikon digital camera, and maybe a 16GB thumb drive for my laptop. Just those three things are all I'm looking for on cyber monday. Any ideas where I can find good deals on these items?

Any and all help will be appreciated!

Try Amazon Black Friday Deals, they have many good deals there http://www.amazon.com/...y_deals-20
