Aeropostale has a new coupon code EXTRA30 that works on clearance too! You have to check out the markdowns, make sure to shop the prices: low to high. I found super cute tees you could layer starting at $2.79!
My order was only $13.98 but shipping was $7, I would say in order to get your moneys worth out of shipping grab a few more items then I did. But in all Im getting 2 aero shirts plus 2 more items for around $20 shipped, thats not bad at all!
