Is this venture worth doing? From what I can tell, I can buy around cables for around $1.10 each, would have to buy like 200 of them at this price, and they sell on eBay and Amazon from anywhere to 3-6 dollars. Also, the market seems very competitive as there are a lot of people doing it, but the demand seems to be pretty big as well. I think the part that will kill most of the profit is shipping. Ideally,could anyone more experienced than I please estimate roughly how much would I be spending to ship each cable? Thanks for your time.
