Hello mark_fleeton:
You can always try an Apple store if there are any in Seattle that are nearby, or you can buy it from TopMic. Now I know you dislike the idea of buying online since you mentioned "physical store" but whenever someone has a question about chargers, I redirect them to TopMic. They include real shipping, real lifetime warranty in case it breaks in the future, and 30 day full refund.
The real shipping might appeal to you the most since I'm assuming you hate to pay for shipping.
Best of luck.
