what kind of customer for dollar store?

Well as a self proclaimed cheap bastard, I once was a dollar store
customer. Once, before I had much cash to shop.

Most, strike that, ALL of the products I ever bought there were worth
about a quarter.  I have moved up in the world, particularly on buying
things.  I do indulge my childrens toy request there with a buck here
and there. So, it is a great place to satisfy a child's toy purchase,
but again, its cheap crap.

I now shop at Target....Well, at least a great deal of my check, and
my wifes time is there.

Thank you for your question.  
 
However, I believe that to answer it well, your question will require
more time and effort than the average amount of time and effort
associated with this price. Here is a link to guidelines about pricing
