I own too much Staples stock "to move on"...And had you been reading,you would find that there is a program that precisely fits the bill.
But, SINCE YOU ASKED(again):
It is low cost(far less than our newspaper inserts). It reaches SMB decision makers at their place of business. It has HUGE numbers. It surround-mails SMB retailer locations and covers areas near 93% of all Staples store locations across America. It delivers recipients that for the most part are NOT current Staples clients. It has a shared mail component that allows Retail circulars(our size) to be inserted.
If this sounds interesting then I will dig up the last article and send you to the page by posting it here. But lets see if anyone from Staples Marketing steps up and asks.
