Edited to add Etsy's checkout procedure:
* Add item(s) to cart
* Go to checkout
* Add your address
* Choose Paypal an click Submit order (big green button on the right and bottom of the screen, if you don't complete this step I won't be able to see which items you're ordering and can't send you the discounted invoice)
* This finishes the Etsy transaction, after this you just have to wait for my email.
