Maybe you could go to Dollar General's website and perhaps there's an email address where you could write them. Ask them if they know where you could find the Clover Valley clam chowder. Or, see if Clover Valley has a website and ask them the same thing. Most companies will answer and tell you what stores in your area their products are sold.
I know I've seen Clover Valley at Dollar General but don't know if I've seen the clam chowder tho.
