My own personal opinion is that there are so many recipes available on the internet, plus there are many stores that carry "buffalo wing" sauce, that it would really have to be something special to entice me to order off the internet. Now, bbq sauce is another matter, only because there is more expense involved in making your own, where wing sauce is fairly inexpensive to make.
