Luis,
Agree, sell to small fruit vendors, is better than those big chain stores. You'll make more that way, if sold to the big store, they would want whole sale price, then you don't get your money's worth. And when they start selling your fruits, they will charge like that price you had bough that one fruit above. So, thy'll make more than you, unless, you have an abundance of plant's producing, then maybe whole sale would be an option, but for now, going small fruit vendor is a good idea.
Yes, they also have healthy benefits as well, i'm just not aware of which ones exactly. Haven't done much research of their health benefits, but every time, have looked up on DF. They mention some of the benefits.
Good luck and would love a report, once your plants gets going.
