I think that in a business sense, what LL Bean and other good companies like Pelican are reaping is the result of a philosophy of delivering quality at every level. In order to do this, the company has to sell well-made goods and back them beyond what it says in the fine print. IMO, this creates loyal customers like Moses and Sonic, but I would not call it karma because it's too direct.
I always thought of karma as being a little more indirect and working behind the scenes, something that requires faith and belief. And BTW, horribly run businesses can stay open forever in the absence of good old-fashioned competition, I've seen it a hundred times. Haven't you ever been in a lousy restaurant (or yogurt shop), and thought to yourself, "I should open one of these across the street and take all of their business in 1 week?"
I believe in karma on a personal level in that every action has energy and results, (intended and otherwise), you start adding them up and you have quite a pile of good or bad energy. I believe in the corny old thing about courtesy being contagious, (and the opposite), that it will reverberate throughout the city in the contacts of the person that you are treating well or badly, etc... The problem for me is that I am a very imperfect human and while I usually treat my fellow man very well, sometimes I don't. I always feel bad if I am less than polite to someone due to impatience or some other worthless excuse for a bad mood, but like a bell that cannot be unrung, the damage is done. I believe in karma on that level, because the way that you treat others chemically changes you; one's actions define who they are and how happy they are, whether you are smiling or furrowing your brow at everyone, etc...
For Wayne, lastly, and most importantly, I believe that the universe (God) gave you that child because she needed great parents and a stable caring household. Children are simply put in the care of other older humans while young on earth, in this one instance she wound up in a good place. Imagine if she had not been so placed, though it is an intolerable thought. If there is karma, it is demonstrated whenever a child with special needs winds up being born to great parents, IMO.
