They used to have the cheaper option but they don't now. You can ship first class through paypal... there is a charge but it may be worth it depending on how many 1st class packages you send a month. The paypal charge is $.20 so you would have to send 80 packages a month to make up for the $15.99. Of course, if you don't take your payments through paypal then you can't ship that way....
HTHs!
Did you already sign up? I could give you a referal so I could get free shipping
