Please note that a wholesale price is very different for electronic Items. If your buying wholesale electronics the wholesale reduction can only be a few dollars.
If your trying to sell electronics on ebay and your not already established I would advise you to steer clear from this area as liquidators already dominate ebay in electronics by buying the products at liquidated prices.
Now wholesale prices for house hold products can be as much as 50% below retail. So this would be a better market for you to sell in.
