I got it at the CVS at my local Target. Apparently all CVS locations have it, or are supposed to.
FYI, the CVS web site said that appointments are not necessary. That is false; ours turned us away and told us to get an appt and come back.
I wad pissed until I saw the reason: severe understaffing behind the counter, end of year prescription rush, pharmacist at the end of her rope.
