The product I made was a necklace. The pieces used were a foot of chain and a door knob. The door knob costs four dollars and the chain cost three dollars a foot from my local supply store.
3$/ 1 ft
4$/ 1 knob
9$/ .25 = 9.25$ (Total Cost)
+ 20% profit ( 1.85$) = 11.10$ (Total Cost + Profit)
Suggested Retail Price = 23$
