The American Express Master Value Injection (MVI) is back for 2021 for Personal Platinum cards at least. They now give up to $30 per month in PayPal statement credits, which I guess is a barely passable replacement for PayPal Key no longer working with AmEx. Call it the Master Value Injection 2.0. This is good from January 1 through June 30, giving you 6 months * $30/month or $180 in total credits per Personal Platinum.
I personally would buy discounted gift cards for resale from anywhere but PayPal Digital Gifts when a deal comes up, or use Fluz with PayPal checkout to liquidate these credits. I suppose you could also be basic and liquidate via real purchases. Fluz has a pyramid scheme built into it, so find a friend for a referral if you haven’t used it before, or contact me for one if you don’t know anyone else.
There’s some bad news too though. American Express is again charging the excise tax for transferring miles to US based travel partners (Delta, Hawaiian, JetBlue). Call it the Master Value De-Injection. Ok, so this resumption was due to the CARES act suspending the taxes until 12/31/2020, not AmEx directly; but whatever, I still blame AmEx for charging it in the first place.
