Where did you previously ask me what state I live in?
I'm in Michigan.
The other thing I have found, that for some reason, most retailers around here (Little Rock, Arkansas) seem to have supply issues with products containing this ingredient. It is not unusual to find that when you carry the little card from the shelf to the counter, they say sorry - we are still out. So - the answer - buy a few boxes when they DO get some in... Oooppss... cant do that either. Strict limits on how much you can buy at one time.
I've never taken a little card to the counter. I just go to the counter and ask for the pseudophedrine, I sign some piece of paper, they give me the stuff and I leave. I've never had them be out either. In fact, they usually have a couple of brands to choose from, including the cheaper generic brand.
I asked it in general in reply to another post, not of you directly or specifically.
My issues must be just another among the myriad of issues in Arkansas...
