I'm afraid that low (or no) funds are a cross we affiliates need to bear. I expect
that the accounting departments of smaller businesses experience cash flow problems resulting from their cross' to bear which is, in part, from returns and refunds after payments are made to small affiliates who have no pending cash in their accounts from which to debit a refund to the merchant.
I would speculate that merchants have, from time-to-time suggested witholding our affiliate payments for a longer waiting period.
Besides (tongue-in- cheek) why worry about deleting "offline" ads when Norton will delete all our ads for us. grrrrrrrrr
