Mercantile store is erroring on Canadian Credit Card

[meaganhanes]

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??

Just wanted to note that Meagan and I chatted about this and it *seems* to be related mainly to the specific bank / card.

I will continue to monitor this for further issue, but other Canadian cards are processing properly.

I believe @slash1andy pushed an update that may have helped with this situation. Shall I make a verifying purchase to confirm?
