Free trial membership on back-to-school swapping site

If you missed the June free trial at ThredUp, an online kids clothing swap, here's your chance. Join ThredUp now and get two months free OR 20% off in August. Use coupon code mysavings. Not sure if the code is case sensitive. Expires September 1, 2010. Click on the image at right to get the deal.

Here's how the site works: You pay $13 to receive a box of clothes; sending a box is free. Each box has an average of 15 items, or about 87 cents per item. You can chose from dozens of boxes listed and search by sex, age, and types of clothes you want.

The free trial is for ThredUp's PRO membership, which is $20 for six months or $30 for a year. A basic membership is free. I'd go for the freebie and you can always cancel if the program does not meet your needs.
