Query: flawed filter, flawed shipping/return policy

When I took the filter out of the box and held it up to the light, I thought it was scratched, but there was a "fold" or flaw in the glass of the filter, a little more than half an inch long. I returned it for a refund. The original shipping was $7.95. The return shipping was $5.81. Had I bought it straight from Adorama, their shipping would have been $5.00. I'm out $13.76 for shipping on a defective product from a company that has a return policy stating, "Please wait 8 days from date we received the package for us to process your return." Also, I question the legality of Amazon's practice of charging credit cards for third-party items when they're ordered and not waiting until they're shipped. The moral? Watch shipping and return policies when you buy a third-party item from Amazon.
