If you purchase gifts from a major retailer, and they are returned they are likely to end up in a landfill.
Major retailers has assess the cost for returned items and repackaging them. If it's cheaper for the retailer to throw out returned goods rather try to resell them, they end up in the trash.
A like-new item or piece of clothing might be able to be resold at full cost, but most returns are used or damaged. A recent retail survey found that less than half of all goods can be resold at full cost.
The National Retail Federation estimates 15% to 30% of online holiday purchase will be returned -- about $32 billion worth.
This issue makes it even more attractive to buy from a craft person, where you know they can repair the items or make sure the raw materials are recycled.
