I am very satisfied with ChargerBuy.com. I needed a charger for my Lenovo Yoga ThinkPad and was getting nowhere with our local retailers. When I found Charger Buy I simply entered what I was looking for and the brand and model of my laptop. It came up right away and they even had it in stock for less then half the price then if I had ordered from Lenovo. After ordering it took about two days for shipping. Works great and has a two year warranty.
