I'm doing a little informal research to find the best deal in neodymium magnets. The price per cubic inch seems to be extremely variable- some on the order of $10 and others in the hundreds of dollars. Can you find a better deal than I did?
Conditions on the order of NdFeB magnets: * Total price, including shipping to the US, under $30 * Contains at least four magnets with intact coating * Contains a total of at least 6 cubic inches (98322mm^3) of magnet
The best I could come up with is $4.93 per cubic inch. Can you find a better unit price?
