Caveat about the Cable Company return policy

I have used the lending library many times and that has been a great help in buying cables, I find that they price with a fair discount which would bring me back for future purchases. However I did buy a cable that was a closeout at the salespersons strong recommendation and when I tried it I found it too bright. Then tried to return it and that became a challenge as the salesman was bent on me keeping that cable out of their inventory. The persistence reached a level of I should practically rebuild my entire system around the cable. Well being persistent myself, I did finally get a return authorization. And my solution was to find another salesman within the company and have had good luck on purchases since that one transaction. That said, I do understand them not wanting to accept returns on “non-stock” items, as a business they must maintain profitability and at best a re-stocking fee or credit towards another purchase could be a fair compromise for both parties. But they know what they need to do to stay business, profit is not a four letter word, and the decision is theirs on acceptance of returns and our on doing business with them. They have yet to give me reason to cut them off. But their return policy needs to be clear at the point of sale.
