Affirm isn't the only BNPL for Costco gold.

If you're running the Costco gold play, you've probably already got Affirm in the mix for putting Amex spend through it. Affirm is the well-known one, but it isn't the only BNPL that works, and there are plenty of others worth a look.

Sezzle Anywhere is one. It runs $20 a month for the membership, but it lets you push $5k of Amex spend a month through Costco, and that $5k earns an extra 1% back. That's $50, so after the membership you're netting about $30 a month. The $5k cap also seems to get enforced only sporadically.

$5k a month isn't a huge number, but it's handy if you're ever scraping to hit Amex spend for whatever reason, and the extra 1% is a nice cherry on top.
