Now, not that I'm averse to the idea of selling ideas, but what ideas are sold at:
Food & Drug Stores
Semiconductors and Other Electronic Components
Two entry in the idea-selling list I found are: "Computers, Office Equipment" and "Mail, Package, Freight Delivery". Equipment to create ideas (or store ideas) and shipping ideas, yes, that might be the case, but still doubtful IMHO.
Who can enlighten me?
