It is not so easy to figure out how to apply a coupon code on Etsy. I found a screen shot on etsy and altered it with these red arrows and such.
I wish Etsy would simply have the coupon code box on the checkout page without having to click on the blue link to make it appear. But for now this is how it appears. I’ll link to this from my shop announcement. Anyway, have a great day and thanks for stopping by. Hope this helps! – -Natalie
