Honestly the best way to make money leave electronics alone
buy in bulk you dont have to get a 20 foot pallet but small bulk to start with take jimmys site for example start out with the profit packs and work your self up to larger orders you can honestly make good money off of sites like his these dropshipping sites are good for your own website but not ebay I tell people to keep some stuff on hand and use a dropshipper for a filler that is if you have your own website.
What I mean by a filler is your site should revolve around what you buy wholesale then add dropshipping items to make your inventory seem larger.
