The GoW 'Sample Program' works this way:

Each order [unless we run out of samples] will be delivered with a sample size product. 
Once you receive the sample and have given it the test run, your feedback
would be greatly appreciated.  This can be done directly on the
forum or through e-mail directly to GoW.  gardenw@q.com

This is our way of offering finished products with our customers satisfaction being
the main goal.  We appreciate your business and hope to have
a long and beneficial relationship.
