As always, merchants game their category to manipulate the discount fee... I've had shipping vendors with "USPS Postage" contained in the name and it gets classified as "Employment Agencies" . Amex rep says the discount fee is lower on employment agencies and there's not much enforcement

Anyways I went ahead and bit the bullet by upgrading legacy Gold into Business Gold. 4x MR points (up to 150k a year) for $295 annual fee is too hard to pass up . I'll run it a few months and can contribute some data points (just like Ultimate Rewards) if the data is useful.
