http://www.realsimple.com/realsimple/package/0,21861,1685433,00.html?nid=-1685690 is a link regarding a shopping guide to Black Friday. I especially like the topic regarding the best time of day to return merchandise. (1st hour of the shopping day because the best employees have the best hours and they start out at their assigned posts). Another topic discusses the best savings for holiday shopping. I wasn't aware that Coinstar will issue amazon gift cards instead of cash and a high user fee. Last, a study has been done showing that clipping coupons doesn't save you money unless you were planning to buy the item anyway.
Happy Thanksgiving, and good luck on Black Friday!
