Has anyone ever bought dried oregano that smelled or tasted off?

The first time I noticed this, I wasn't sure what it was. I bought the
Italian seasoning from Costco. It had a musty odor to it and it didn't
taste good to us. I think it was a Mccormick seasoning but it was different
than what I usually buy. I think it said "Northern Italian" or something.

I just assumed that we didn't like it and I threw it out.

And now I have some Archer Farms oregano. I notice that the aroma of it
when I open the bottle is very strong/sharp. I can't really tell if it is a
different aroma than usual. I will have to buy another brand and compare
them. And there isn't the must smell. But it seems to have an off flavor.
I thought at first that it was just stronger than usual. So I used less of
it. But that didn't help. Gives an off flavor to my dish. I will buy
another brand tomorrow and see if that is better.

Oregano is one of the herbs/spices that I have been using for years. And I
used to put a ton of it in my red pasta sauce. I am not brand loyal either.
If I need it, I will buy it wherever I am and will usually get whatever the
cheapest stuff is. That could be the 99 cent stuff at the drugstore, but
usually it's McCormick or Schilling.
