$10 at ThredUP

Okay, this isn’t a printable freebie but it’s worth $10.

If you click on this link you will get $10 to use at this kids clothing site when you sign up for an account. You can also use promo code AUGUST20 to get an additional 20% off.
The credit will cover shipping costs (starts at $6.95), so if you find an item in the $4 range, then you should not have any out of pocket expense (no need to even enter your credit card info!).
