Ebay is great to have access to but I think you have to move a lot of merchandise to make some money, and will it be a consistent income. I have some friends that have done okay with the sales but they have a business.
There are many legit businesses in the marketing department. I know, I have tried a couple and found one that was a public need! Identity Theft a concern today? You bet, and it's not getting better so everyone should have some sort of protection. Sure there is a bit of a learning curve but like with anything you have to know what you are doing so some effort is required. Always do your research.
