I'm having the same problem, as well as a friend of mine. We both bought e-gift cards yesterday, 5/7, both of ours were for Kroger, and still haven't received anything. It's been more than 24 hours since the purchase. The transactions went through on our credit cards immediately (of course). I've never had this problem before and have purchased several e-gift cards since i joined AARP two years ago. Usually I receive them within a few minutes. I found a 2019 post in this forum where someone had this problem, and he stated AARP told him it could take up to 72 hours, which is absurd.
Update: I still have not received my e-gift card for $50 for Kroger. I've looked at past posts on this forum and it appears there has been a significant problem with AARP e-gift cards failing to be emailed within the 24-hour period since January 2022. Since this is probably a software issue that needs to be resolved, I hope someone is actively working on it. FYI - I checked my SPAM folder and it's not there either.
Thank you!
