John,
As I said above, saving the foam inserts is a collector's preference. The early pieces came with peanuts so it is a no brainer there. Peanuts is Peanuts and I challenge any collector to tell the difference between HL peanuts or Walmart peanuts. The later lights came with foam inserts and seeing as how most of these have no secondary market value so to speak what difference does it make whether you get $25.00 without foam or $30.00 with foam? It's all collector's preference.
