I stumbled across the SlickDeals.net Forums' Excel Spreadsheet - BF Filtered Ads - BF2008 Buying Guide yesterday and thought this is a useful spreadsheet for anyone looking for shopping deals this week. They look to be keeping the spreadsheet up-to-date, so it's worth checking again later to see what changes may have been added.
This list seems to have ads from just about every major and is a great way to compare prices between companies to find the best deals. The spreadsheet also allows for easy filtering to specific categories/headings and allows you to choose the sort order of the fields.
So, if you're trying to map out the stores you should be visiting over the next couple of days, I recommend downloading this spreadsheet right now and looking it over.
NOTE:You can even view a Google version of the spreadsheet (which doesn't require that you have Microsoft Excel,) but I haven't been able to access it this morning due to the volume of people viewing the document.
