What is the laptop to be used for?
If it's only for internet browsing, school work, social media, etc, then almost any cheap laptop can do the job (although wireless capability, so that it can connect directly to your router, would obviously be an advantage). But laptops which can play the latest 'all action' games require a lot of computing power, with fast processors and top-of-the range video cards; they don't come cheap.
So we need some more information from you. In the meantime though, I'll recommend a company which I have total faith in. They sell both new and factory-refurbished laptops at very reasonable prices, and they've got excellent customer service:
