From what little bit I looked. (gnc, bb, nutraplanet) There are 3 deals here, Battle Fuel, Compound 20, and the Fat Burner. The Supreme Protein bars aren't a bad price either, especially when you consider that most people buy them at their local gas station/grocery store for over double the price woot has them for.
Both MusclePharm and USPLabs have quality products, but I haven't ever tried these particular ones. I'm always hesitant to buy supplements off of Woot, or any overstock place for that matter. Seems like old recipes, and old batches of stuff would end up there.
The protein business is weird though, a large majority of companies order their protein through 1 outlet, and then add their "proprietary" additives and flavors. Thing is, you can order your protein from this same outlet, and eliminate the middle man. Google "True Nutrition" and build your own higher quality protein, or a cheaper if that's the avenue you want to go.
