See the fine print that applies to all Mamasource deals

The Company

thredUP was started in 2010 by a group of men—led by a new dad—who recognized the need for an efficient, affordable, and eco-friendly kids’ clothes exchange service. Browse boxes of clothes available to buy, or earn money with each box you send in. The small company is based in San Francisco, CA.


thredUP is an online baby and kids clothing swap- and after giving it a try, I have to say it’s my new favorite way to buy second-hand. No waking up early for yard sales, or standing in long consignment lines. Just inexpensive clothes from the comfort of your home and the convenience of your computer.

Stress-Free Promise

We’re not happy unless you’re happy. If you experience any problems with the redemption of any Mamasource deal, just reach out to us and we’ll work with the vendors to make sure that things go smoothly or are otherwise resolved by them in a fair manner. If that doesn’t work, we will give you (the original buyer) full credit for your original purchase that you can use towards future purchases. (Credit can be used on Mamasource deals only and not valid on partner sites. Credit must be requested within 45 days of purchase, and used within 90 days of issuance, and are limited to 1 per customer or household per 45 days.). Please review our full policy here.
