Reply to comment by robotsquirrel in U.S. orders Mastercard to stop blocking competing payment networks by HRJafael

Are you talking about this?

>If you've got a card from American Express or Discover, then the card issuer and card network are one and the same company.

Because if that's what you're saying you're interpreting it wrong, what it means is that (unlike other banks) both Discover and AMEX are both the bank that issue their cards to customers as well as payment networks

I have been to many businesses (especially in other countries) where it's common that they take American Express but not Discover, and also the other way around here

But even then that information is not completely correct, I have a wells Fargo card issued by American Express gor example

That's cool. It doesn't change the fact I used a Discover card in one state and a completely different one a year later at a brand new Costco.

Well I can't find any info before 1999, which was the year Costco signed its exclusive agreement with American Express, so it was either before that year or you used a debit Discover card, since to this day Costco takes debit cards on any of those payments networks
