This is a planning page for the various kits we're developing. We will be offering free online plans for all of them, but are also interested in selling the materials, since some are only available in bulk. For the [balloon mapping](/tool/balloon-mapping) kit, we're considering offering a low-cost version and a higher-priced, but identical one. Those with the money to spare, who are interested in supporting further research at Public Laboratory, can purchase the more expensive one. ###The Balloon Kit### * $11.89 - Kite reel * $10 - 3000' string * $2.99 - mylar sleeping bags * $3.49 - rubber bands * $0.50 swivels * $6.92 - gloves (optional?) **Total price at cost: ~$35 + shipping** (planning [google-doc here](https://spreadsheets0.google.com/ccc?hl=en&key=tmtUNkUn9wjS-PIPXtr6GXQ&hl=en#gid=0)) So, I propose: **Base price: ~$50** **"Sponsor" price: ~$100** ###Things to consider at Retail### standard retail markup is 40%, I think we should pick a base price markup and apply it to everything we do. we also have to warn people of anything they must add, like helium, which is as expensive as the whole kit -mathew
