[Evergreen-general] Stripe Duplicate Charges

[Terran McCanna]

We still see it sometimes when a patron has a negative bill on their
account (even when the overall balance isn't negative).
The current code shouldn't even be showing the payment option if there are
any negative bills, but somehow some patrons are still getting the option.
We have been on the new code for a long time (more than 2 years?) so the
only thing we can think of is that those patrons must be using an old
device that is stubbornly hanging onto a locally cached version of the
page. But we haven't been able to recreate the problem, so it's really
frustrating to troubleshoot.

As far as I can tell, what is happening is that the patron somehow loads
the old version of the page that didn't do the negative bill check, pays,
Stripe accepts the payment but it's the wrong amount, so when Stripe sends
it to Evergreen it fails. Then the patron sees that Evergreen didn't accept
it and they pay again (still the wrong amount), causing their credit card
to be charged again.
