Buy and sell domain names:
A domain name is just a website address (eg. ‘savethestudent.org’ or ‘mysite.co.uk’) and there are lots of extensions (.com, .net, .co.uk etc).They cost as little as £1.99 to register with 123-reg.co.uk or GoDaddy.com yet premium domain names can fetch £1,000s if not millions when sold on. In 2007
VacationRentals.com went for a cool $35m! Now you’re probably not going to come across anything like that, but you can still turn a quick profit with a bit of searching. The trick is to find available domain names which have some commercial value, snap them up and then list them for sale on a site like DomainLore.
