The 35k offer on the SPG Business card only lasts through today, March 28, 2018. If you're interested, it's time to pull the trigger.

In July of last year I published a post welcoming readers to share their American Express card referral links in the comments. Since many of the offers in the comments have expired, I decided to start fresh with a new thread in January.

Last month my good friend and CPA wrote to me with various  questions regarding the hobby. He touches on a few pertinent topics that I think are worth sharing with you guys.

My response is in normal font and his original questions are in italics. Anything I added to the email to better explain something to you guys is in blue and in parentheses.

For a while Hilton has offered all of the following co-branded credit cards:

Hilton Honors Card from American Express with no annual fee
Citi Hilton Honors Card with no annual fee
Hilton Honors Surpass Card from American Express with a $75 annual fee
Citi Hilton Honors Reserve Card with a $95 annual fee

But that's changing tomorrow. We've known for a while that Hilton dropped its partnership with Citi in favor of an exclusive co-branding partnership with Amex.

Update 10/26/17: This offer is ending next week, on Wednesday, November 1. Looking back historically, there is a decent chance this is the last elevated offer we will see for the SPG Business card if Chase takes over as the card issuer instead of American Express moving forward with the SPG/Marriott merger.

We've been seeing a lot of valuable Amex offers for Amazon purchases lately, which I'm all for as we all probably spend on Amazon anyways.

American Express is offering a couple lucrative incentives to spend on Amazon with their Membership Reward earning cards at the moment.
