I just got an email from them...and I just had to share an excerpt of it with you! This is just another reason why I love their site :)
We did it! ShopHandmade crossed its first major milestone by listing 5,000 items for sale in our first month after opening! We chose to celebrate the event by planting 5,000 trees – one for each product listed. As they take root and flourish, we hope that this early success will echo forever in their leaves and branches.
