If you're in the US and want a cheap computer, Dell Refurbished sells off-lease desktops and laptops. I.e. companies rent a computer for some number of years, then it goes back here, they might refurbish it slightly, then sell it. The store is run by Dell's financing subsidiary.
These are all business-grade computers, so better built than cheap consumer stuff, albeit used.
In addition to being cheaper, the carbon emissions from buying used computers is vastly lower than a new computer.
IMPORTANT: If your goal is to save money, only ever buy when there's a coupon or "hot deal". The coupons and deals change frequently depending on how much stock they have of specific models, so check back every few days.
For next 24 hours they have 48% off coupon for all Precision laptops, which are Dell's workstation-grade laptops.
