The main reason I have hesitated to purchase from thredUP before has been the $40 minimum they require for free shipping - it doesn't save much money to buy a used item for $3.99 if you have to pay $6-$7 for shipping! However.....for the rest of October, thredUP is offering free shipping on all purchases - no minimum required! Just enter the code "SHIPOCT12" at checkout and get your shipping completely free for the rest of the month!
I just purchased a few items for my 2 year old - a few weeks ago when I pulled out the bin of hand-me-downs from her older sisters, I realized there were only a couple pairs of long pants that survived! I bought 5 pairs of pants and only paid $22, which I feel was a pretty good deal for the items that I got especially since I didn't have to leave home or search around for more than a few minutes to find these deals!
Here are a couple of examples of the types of items available:
24M Children's Place jeans only $3.99
18M Children's Place Hoodie only $3.99
