What are good items to buy and resale on ebay for a higher price?

Hi, I have been searching around and I want to know what you guys think is the best item to buy and resale that will sell for a higher price on ebay. I prefer electronics but anything is fine. I know ebay charges the fees so I know that plays a factor also. And also, do you guys know any wholesale sites to buy in bulk for a cheaper price? Thanks, best answer gets 10 points
