Returns Policy for Business Users

I have had a number of buyers who have purchased an item and then on receipt have decided that they "don't like it".  We find this particularly irritating as out listings are very detailed with lots of photographs.

 

While i appreciate that the buyer has the right to return, I do not see why we should have to bear the cost of the postage to them.  In some cases the cost of the postage is a substantial part of our profit and the time spent dealing with a return reduces the profit to zero.

 

Is there a way in which we can have a returns policy that ensures that the buyer pays for the postage that we incur as well as the postage of the return in the event that it is a silly reason such as "I didn't like it" or "I changed my mind"!!??

 

We are new to selling on Ebay and would be grateful for any advise as how to deal with this and recover our postage costs.

 

Thanks
