For some reason we haven't sampled Costco's rotisserie chickens, but we have chowed down on a few from Sam's. Even received a free one, apparently they give away all the ones still on the spits when the stores close; or at least that's what they did the time we were checking out during closing.
From my observation, it seems Costco's chickens are a little bigger, but I could be wrong.
I'm sure any person who has watched late night TV has seen the ads for
Ronco's rotisserie machine. Well, I have to tell you, that machine really does deliver a good product. One of my daughters has one, and has fixed a few for us.
Looks like
Ronco is hawking three different models of rotisserie's, nowadays:

Though, why do it yourself when it is just as cheap (or cheaper) to let Costco or Sam's do the cooking?
Our local grocery chain,
Publix, prepares a good rotisserie chicken, also. The lemon-pepper and mojo flavored ones are my favorites.
