  Keep in mind that, as with any other Clickbank product, the buyer has 60 days to request a refund in full. I think that gives the actual buyer plenty of time to check out the product and see if it was worth their money.
  The refund rate of any product is important to consider when choosing what product to promote. If a product is refunded, you don't get your commission.
  Particularly, I have found that GreenDIYEnergy converts much better than Earth4Energy, even though Earth4Energy's gravity is higher. GreenDIYEnergy claims to have a very low refund rate as well.
