Buy one, get one sales are the oldest merchandising trick in the book. Buy one, give one promotions are a more recent, and more satisfying trend, set in motion by socially minded companies like TOMS Shoes.

The latest to jump on the ‘bogo’ bandwagon is Peace Love World, a line of ultra-cool T-shirts, sweats and casual wear with messages of peace, love and happiness. When you buy any tee online in 2011, the company will outfit a deserving child in his or her own smile-inducing Peace Love World shirt. Many tees have already been donated to children in Haiti and shelters across America.

Peace Love World is no stranger to charitable promotions. The “I am Hope and Love” shirt is dedicated to raising awareness for Breast Cancer issues. Their “Don’t text and drive” campaign aims to stop the dangerous practice before it becomes our next national epidemic.

Alina Villasante is the vivacious, creative founder of Peace Love World. It started simply with a T-shirt advocating a strong message of love that she designed for a friend. Now the company has transformed into a full-fledged business with every garment branded with Alina’s mantra: “Love is not something you look for, love is something you become.”

Taylor Swift, Chad Ochocinco, Ellen and Flo Rida have all been seen sporting Peace Love World designs. The buy one, give one effort offers a bonus reason to wear one of these feel good items, and up your own quotient of peace, love and happiness!
