As pointed out that once they are in the retail stream, the manufacturer loses any rights to control the further resale. You can not however, advertise them as new (you can say unused, unopened) but when you bought them, they ceased to be new.
Craigslist is not a "local store."
I suspect strongly that your business model is highly suspect. Why would anybody pay more on ebay for something than they could get by buying direct from Best Buy (which pretty much sells the same stuff on line as well). I'd be really surprised if you even made enough to cover the ebay/paypal fees let alone make any sort of profit.
Note that if you make a business out of this, you will still be required to obey Virginia laws and collect and remit sales tax on sales in the state (and you must submit the periodic forms even if you make no in-state sales in that period).
