I have about six boxes I like to keep on hand, well five because one was a limited production. The rest are purchases of fivers that are also staples. Then there's the singles of new stuff must have. Well and a whole drawer o singles from passes pifs bombs maw.... If I burn through a fiver fairly quick I know whether it's box worthy or not. When finances allow it becomes a box. Cc are box only as I've yet to have a bad one.
