Here’s an interesting way to curb your spending this holiday season ... a purse that yells at you. I needed this the last two days. 

Three students at Dundee University in Scotland have created a messenger –style bag that actually yells at you when you take your credit card out. It says things like: "Do you really need this?" and "You're already in over-draft!" when sensors notice that your credit card is out of your bag. Amazing.

One problem: It isn’t for sale. The bag was a project by the students to illustrate our consumerist society.

It doesn't really help with online shopping though...
