In my business, I work a lot of returns processing for my customers. Couple of things to ponder:
1. Is the return worth salvaging. In a lot of instances, the cost to rework the product doesn't justify reworking it, so we just receive and discard.
2. Consumers, if unhappy with the product, don't like to have to spend postage to return it. They are already unhappy, and if #1 is the case, better to just refund purchase price and let them keep the product anyway. No sense making them madder by having to cough up $5 for postage etc.
3. I've seen what consumers return sometimes. I've seen people return other products under and RMA then get mad when they don't get credit back.
4. The guarantee should be used to diagnose problems with your product. If a consumer is unhappy, use it as a tool to learn what you can do better.
5. "satisfaction guaranteed or your money back" is a marketing slogan to instill confidence in your product.
Hope this info helps
