I have been using the Sams Club Rogaine for years now and I like it. It is such a good deal. Like 12 bucks for 4 bottles. What i found interesting was, about 2 weeks ago I ran out and just bought some generic formula called Equaline or something like that from a grocery store (Albertsons). The color was completely different from my Sams club brand. The Equaline almost had a tint of yellow to it while the Sams club was completely clear. Ingredients listed are exactly the same.
