Following US Thanksgiving tomorrow, Thursday Nov 25, comes Black Friday, the busiest shopping day of the year as Christmas approaches. Here are 5 apps that are supposed to help shoppers.

I downloaded #s 4 and 5, RedLaser and mallmaps, and they seem reasonably useful. RedLaser is a bar code scanner program that gives product information, helping you to find the places that sell the same item at different prices, including online, plus can show more information about the item than may be provided on the store packaging or sales tag.

mallmaps is just what it says, maps of major US malls. Plus it claims to help you find store sales. I found it doesn't show the smaller South Florida area malls, but at least does have the larger ones I shop. They're both free.
