I was. And I'm still ticked off at CVS. They're "in network" with my coverage, and gladly gave me the 1st shot for free. Come time for the 2nd one, they were out. Call back next week, you might get lucky. I called back once or twice a week for two months. Same story every time. Sometimes, just to add insult to injury, they'd mention they'd had it in a few days before, but it was gone now.
They said they wouldn't bother maintaining a waiting list, I'd just have to keep calling back. Seriously? It's easier to answer the phone dozens of times than to just jot down my name?
After my 2nd shot was already overdue, I called around. No-one had it, but Rite-Aid/Walgreens was willing to put me on their list. But when I mentioned I'd already had the 1st shot, they said they'd just gotten some in, and because I was already overdue, I'd go to the top of the list. I ran right over and got it then and there. Had to pay a co-pay, but I'm glad it's done!
