How Do Your Manage Your Product Returns?

We had a great guest post by people from Amasty that deals with product return policies. And while it deals more with physical product returns, it got me thinking about products returns for a software product, like Magento.

I wanted to find out how you, as Magento devs/providers, manage returns on your services/products/extensions? Are there any specific ideas/practices that helped you decrease the number of refunds/returns? Share your experience in the comments below!
