I've been an Amex Merchant for 40 years now - they sent my a very expensive heavy Crystal vase recently as a “Thank You”.
The cost for me to take your AMEX is less than your Visa and Mastercard costs me, most especially for foreign buyers of which I have many.
The decades old reality of it being 'expensive' to business is just not true now.
As to this PROMO ..... big yawn sadly, to me anyway.
6 cash injections of $10 a merchant spend, as in past years was far savvier IMHO.
As a comment - to speak to ANYONE at Amex these days who is based in Australia, seems near zero in recent years. I truly cannot understand 50% of what many say.
