Apparently people can make money copying and pasting...it's some what true
This is how it works but please do bear in mind that it's a process that needs to be done everyday
Cut long story short all you need to do is find amazon promotional products like the deals of the day and just list that very product on ebay until the promotion is over. Make sure you have a paypal account, one other thing is its best to start with some money because paypal may hold payments on items you've never sold before, so that money you have pre hand would be helpful purchasing goods if you do fall into these circumstances
You will just need:
Amazon account: free
Ebay account: free (you don't need any subscriptions)
PayPal account: free
And fingers lol
