I sent two pairs of Clark's Deser Trek shoes back to the distributor in NY for replacement and recieved four pairs of shoes back, two right away and two more identical pairs a couple of weeks later. It was obvious they messed up and processed my request twice.
I kept both pairs a couple of weeks and I could not get it out of my head that God has blessed me so much that I could easily buy two more pairs of shoes if I wanted them and I should call and tell them what happened and send them back.
When I called, the CSR told me that the cost of shipping them back and restocking them and explaining it all would be more work than it was worth and I'd enjoy the shoes for the next few years and to keep them!
So, different story, same result. Honesty is always the best policy!
BTW, Desert Treks are possibly the most comfortable casual shoe I have ever put on my feet and I highly recommend them (no, I don't work for Clarks!)
