I am not related to them in any way but I would recommend you to use privacy.com to control charges against your cards for situations like this. Capitol One has a service called 'Eno' and Citi has 'virtual account numbers' if you have either of those services they can also help you control charges in a much more granular way than using a regular credit card. Hope this comment helps someone like these services help me.
