This is frustrating.
Again, you guys are avoiding the question. I don't understand why you guys are doing this. Not only does it waste your own time and mine to be answering a different question than the one asked, you're also repeating a point others have gotten across already [1] [2]. Could you please,
please actually read the question? I had very clearly and specifically asked about the
same kind of card (which, lest you found the word "kind" unclear, I explicitly gave an example of: assume
both cards are "Visa Rewards Signature"), for the
same product, with the
same merchant, processed in the
same manner, etc. The
only difference I am focusing on is the card perks (which, again, I gave an example of lest it was unclear: 1% vs. 2% cash back... or 5x points vs. 3% cash back, or whatever you can imagine) or perhaps the issuer (Citi vs. Chase vs. whatever). Somehow you guys are ignoring everything I've asked and repeating to me how merchant fees are different based on the card type (debit vs. credit), card kind (signature vs. regular), merchant (big vs. small), product (groceries vs. gas), etc... yes, thank you, I understood that part already [2], and I was very, very explicitly
not asking about those:
> if I'm buying two of the same product (obviously -- I'm not talking about two gas vs. groceries here) with two different cards, both of which are from the same network and the same "kind" (by which I mean the categorizations listed above, like two that are both "Visa Rewards Signature"), then the merchant will pay the same fee, right? i.e. it's not like the mere fact that one pays 1% cash back and one pays 2% cash back could possibly result in a different charge to the merchant by itself if they're both (say) lumped together as Rewards Traditional?
