1.) How many 4 mil. NB ad's should a person participate in? A? The only answer I have heard to this is one ad per million np's you sell in a week. Do others agree with that? 2.) How much backup NP's should a person have in the till when at the main market level? A? Never seen this answered personally I like to keep an extra 10 million on me. However I am starting to wonder if that isn't to much, and would be better invested in size upgrades. 3.) Can you ever have to many pages of inventory?
