http://www.thredup.com/FAQSeveral pals of mine are taking part in a mass baby clothes exchange, and you only have to pay shipping. I think it's a great idea, but I'm waiting to see if I have a girl on the way...then I can just try to mooch off of Hangers...
How does the exchange work?
Very simply put it works like this: pick a box you like, pay for shipping and handling, prepare a box of items that no longer fit your child, when someone picks your box, send it for free. Here is the step-by-step version:
PICK - Browse boxes listed in the thredUP community and select one you'd like to receive. Hopefully, by now, you have your friends on thredUP so you can just pick their boxes. If you're busy, tell us your clothing preferences and the experts at thredUP can choose a box for you.
PAY - Once you've picked your box, pay the shipping and handling fee to have it delivered.
PREPARE - As part of this process, you are required (this is a swap after all!) to list a box of clothes that your child no longer wears. We'll ask for basic details such as number of items, colors, brands and sizes. Don't worry, the USPS will mail you empty boxes for your gently used clothes.
SEND - When someone picks your box, thredUP will alert you and ask you to send this box. It is free to send boxes on thredUP because the recipient pays the shipping. You'll be able to print the label and schedule the pickup all in one click. Would you rather drop it off at the Post Office? No problem! Just cancel the pickup and leave a note for your postal carrier. As soon as your box is assigned a tracking number by the USPS, you will see your box status has been changed to "shipped" in your thredUP closet.
