You have to remember tho, the cost of owning a wedsite is different than the cost of owning a store with utility bills, employees, taxes etc
probably some of that is just overhead, 2$ is ridiculous but then again its not like that many people buy that kinda stuff these days that they can lower there price and go for quantity sales
If your business model necessitates a 9900% markup then you have some serious problems.
If I can buy a part for $.02, then I KNOW that a business such as RS can buy them for even less in the quantities that they can purchase in.
There is no way to explain away the greed and essential usury.
