Yep, CL is sketchy, legally. My "buddy" bought a 400 watt HPS setup and got 6 clones for free. I'm no lawyer, but given that there are head shops giving away bud with a minimum purchase, I don't see why giving away clones or seeds with a purchase would be any different. They turned out to be WONDERFUL. Occasionally you'll find the grower who is giving up, getting out of it, parents found the grow, etc and they are getting rid of stuff cheap. In the above example, it was $120 for a 400 watt HPS, with nice hood, and clones / teens (18" tall). So, were they $20 clones or a $120 400w HPS? $120 400w HPS is the correct answer.
Given that your "passing through" makes it tougher. But where there's a will, there's a way.
