@tdmalone FYI you can't use that with an SCP, you can only have wildcards at the END of a SCP. I tried similar with *ReservedInstance* and it does not work.

Note
In an SCP, the wildcard characters (*) and (?) in an Action or NotAction element can be used only by itself
or at the end of the string. It can't appear at the beginning or middle of the string. Therefore,
"servicename:action*" is valid, but "servicename:*action" and "servicename:some*action" are both invalid in SCPs.

Provisioned Throughput pricing
An application developer, buys one model unit of Anthropic Claude Instant with 1-month commitment for their text summarization use case.
Total monthly cost incurred is 1 model unit * $39.60 * 24 hours * 31 days = $29,462.40

Thanks @sam-cox-tracebit, added.

I've got one sneaky b*****d to be added to the list:
Amazon Pinpoint-Deliverability dashboard
https://aws.amazon.com/pinpoint/pricing/

The Deliverability Dashboard is available for a fixed price of USD $1,250 per month. This charge includes reputation monitoring for up to five domains and 25 predictive email placement tests.

Note: If you cancel your subscription before the end of a billing period, we continue to charge you for the remaining days in the billing period. However, we don't charge you for the next billing period.

Thanks, added ses:PutDeliverabilityDashboardOption.

Thanks for maintaining this list! 👏
