For those looking to score some easy MR points: I've been noticing a 7k points/$4k spend offer to add an EC to my Biz Plat, which isn't terribly compelling per se, but as I've mentioned before you can redeem them at 1.35x through the refundable-flight maneuver on that card. When I started the process, however, I could choose from four of my biz cards, so I realized I should use one of my BBPs to get 2x on the spend. Then I started wondering if there were a better SUB offer out there, which there was, for 15k: https://www.americanexpress.com/en-us/business/campaigns/employee-cards/business-plus/offer-incentiv.... So I went back in through that link instead. Once I get the card, I'll chat to make sure I got the higher offer, which is an effective 7.7% return. If not, it's still 3.7%, which is a good noncategory rate. Either way, I can then repeat on my other BBP, and if I can get the 15k, on Plat and Green for a 6.4% return.
