Sadly, Plastiq no longer codes 3x on CIP.
Some douchebag blogger for Million Miles Secrets wrote an article about using his CIP to buy a Tesla using Plastiq to earn him thousands of dollars worth in travel, posted it on MMS, which got pushed to Business Insider, Aol Finance, and TPG et al., then got picked up again by CNBC, which then made its way to a Chase internal memo, which caught TPTB’s attention because Plastiq 3x was swiftly shut down. This is why we can’t have nice things. As for that a**hole? He’s gone private on all his social media and is effectively hiding like a coward.
Don’t pay your property taxes with CIP. All data points on and after 8/16 code as just 1x.
If you have aMSR to meet, that’s probably the best use of Plastiq right now. Plastiq also has a Masterpass promo (MasterCard required, but MCGCs should work) that’ll let you make payments of up to $250 fee free, and the regular 2.5% fee after that, until 9/30/18. You can take the $250 FFD or break up your payment into $250 chunks.
