I just browsed through the site and I wasn't too impressed with their sale prices. Found some cute kids clothes for $19.99 and the code gives you $3.00 off, but shipping is $8.00! I don't want to pay 50% of the item cost in shipping. I'll wait until it gets closer to Christmas, they always have better sales.
If you're going bigger, they have free shipping on orders more than $195.00 and then maybe the 15% would make more of a difference.
