Ah, but I've come to expect this from Amazon.
I found THE PERFECT gift for Ish. Added it to my Amazon cart. Knew damn well that it would be entirely possible that things would ship after Christmas and so I was prepared. I was braced.
Six items in my cart. Proceeded to check-out. Edited my Ship To and Bill To addresses. Added a new credit card. And the result?
Five of the items will ship and arrive before Christmas.
The perfect gift for Ish?
Being prepared for this makes it a little less painful, but not entirely.
