Summer etsy store sale

I just wanted to let the interwebs know that I activated a promo code for 15% off on my etsy store. The promotional code is: happyblythe2015.   

I only ship within the U.S. at the moment (mostly because I’m daunted by postage price as it is, and when I calculate shipping on the USPS website for international shipping, the site always spits out rates over $30 D: . What am I doing wrong?)
