TANSTAAFL...

"To get one thing that we like, we usually have to give up another thing that we like. Making decisions requires trading off one goal against another."

TANSTAAFL means that a person or a society cannot get something for nothing. Even if something appears to be free, there is always a cost to the person or to society as a whole even though that cost may be hidden or distributed. For example, you may get complimentary food at a bar during "happy hour," but the bar owner bears the expense of your meal and will attempt to recover that expense somehow. Some goods may be nearly free, such as fruit picked in the wilderness, but usually some cost such as labor or the loss of food for local wildlife is incurred.

So roll up, it's cheap postage promotion time. It's pretty simple from today to July the 17th just use the special secret magic code "SUMMERSUNPOSTAGEFUN" and you don't have to pay any P&P when you order from the Cambridge T-Shirts shop. Not a lot more to it than that, pretty simple.... or is it.... are you paranoid.... or are they out to get you?
