Silly question: Do businesses make money off of issuing fishing licences?

[pinelakeperch]

I've always wondered this, and figured someone on here would know. Curious as to whether I should bother going out of my way to go to a small family owned place to get my licence, or just to CT. I assume the incentive for the retailer would be getting the customers in their store, but I thought they perhaps received a small percentage.
