I also wondered about this one...I have had lots of wholesale orders, but some have not re-ordered from me, one of the stores is out of business but then a good chunk have re-ordered. So I am definitely confused about that too, so I just leave mine blank which is probably the wrong thing to do since potential buyers probably think, "Gosh, they are not carried in any stores." I may have to update to just ones that I have had re-orders from.
