Here is the e-mail :
“The .COM offer will increase to a $4.99 USD price (or the equivalent) for all markets currently at $.99 USD. This change is being implemented for all publishers everywhere. The $.99 .COM offer will no longer be available through any channel with GoDaddy. We expect the change to take place next Tuesday or Wednesday.”
So there are couple of days to save with Godaddy . May 28 or May 29 , 2019 may be the last days to save .
The other .com domain promo codes isnt effected.
