My wife went for the Resy 15x Amex offer. I got an AU card on the account. We're charging away.

But we're having a really, really hard time figuring out which vendors qualify. I cannot figure out any way to reconcile the information I'm getting from Amex. I've called Amex, and they were basically unable to help (not sure if they really even understood the question, frankly).

I have several entries in the "Your Points Activity" page for bonus earn. They all have the description of "K21X:0007 d 14 BNS" along with the Bonus Earn star and the description "These points have been added because of an offer or qualifying purchases made."

But I cannot reconcile these bonus earn points to specific charges. I can try multiple scenarios to get close, but with the rounding, I'm still not even sure. The bonus earn numbers are clearly lumped together, but I just cannot figure out which specific charges they represent.

I'd like to know which charges here are qualifying for our 15x offer so that I can adjust our charging behavior.

Yes, I know I can search the Shop Small map, but that thing is pathetic. For example, my own company doesn't come up there, but yes, charges with us do qualify for Shop Small.

Does anyone know how to crack this nut?
