Bob,
iDevAffiliate actually has no bugs as it is in it's 2nd year now. The reason we have a "no refunds" policy is because so many people purchase without reading all the product information then decide after the fact that they were actually looking for something else. This is a small percentage but still racks up a decent $ amount worth of chargebacks.
We decided to say "no refunds" and make it clear to the buyer that they need to read the product descriptions before making a purchase. We even list on our guarantee page: Do not make a purchase with us unless A) you feel confident our product provides the correct solution you are looking for and B) you feel confident you can correctly implement our software (if no installation was purchased).
If you want to purchase iDevAffiliate, I'll offer you a 30 day money back guarantee and help with your installation. Again, our standard guarantee really only applies for people who don't take the time to review the product, not because the product has bugs or issues.
Sincerely,
Jim Webster
