This is an online service where you can compose a shopping cart from Amazon or Ebay - and get a 3% cut of the sales for anyone who buys it.
Say you sell 100 of a 100 dollar item - you will be rewarded with $300.
If you are selling a good number of high value shopping baskets - this could add up to a few thousand per year.
