 Unable to checkout with valid Canadian Credit Card. Card has now been
 billed and refunded multiple times from the WORDPRESS MERC store but is
 still erroring on the store itself, saying the postal code does not match
 what's on file.

 Steps:
 1. Add items of interest to cart
 2. Checkout with a Canadian credit card, valid
 3. Observe the error in reported postal code issue
 4. Manually fill in all fields instead of using Google Pay. Encounter same
 error. Points to processor interference
 5. Notice your banking app informs you of the valid charge made, then
 immediate refund.
 6. Attempt to change the postal code to match what you know is on file
 7. Step 5 repeats.
 8. Here we are, filing the Trac ticket!

 Potentially a currency issue - the store did auto-change to CDN.

 Interesting error! Happy to help debug further, thanks y'all!
 Priority set to omg bbq because how else are we to celebrate next month
 without this fine merch??
