Drills Sold Per Store
- There are apparently 14,300 hardware stores in the USA 
- Cordless drill market is $4B (verify)
- Average drill assumption: $100 (verify). If that is so - then there are 40M cordless drills sold per year?
- Sounds high, but that's the number.
- Divided by 14,000 stores - that's about 3000 drills per store.
- That is about 250 drills per store per month. Sounds right.
- OSE microfactory production - 60 per month. 4 people to supply a big box store.
