Based on my credit card usages, I have attempted to list down MCCs and bonus points/rebates into the table below. I am working on adding more based on my own transactions.
I am keeping this Googlesheet closed as I personally think that some control is required. But please feel free to email me at firstname.lastname@example.org if you would like to contribute to this list.
In the meantime, please feel free to use this Googlesheet for reference.
