I think wholesale because you have the actual product and I wouldn't really trust drop shipping, not only because I've been there but because you just really can't trust anyone when it comes to money. For example if a company or individual is drop shipping high valued and in demand items for you such as the PS3, and someone comes along and makes them an offer they can't turn down you might be at loss with your customer's goods. Wholesale, you get the best price, and have the security of feeling assured that you have products to sell that are tangible, not handled by a 3rd party.
