Allergan Complete is available in MANY generic store brands, I am talking 100% same ingredients... Costco's Kirkland Signature MPS is actually made by Allergan. Walgreen's MPS is also Allergan Complete. RiteAid's MPS is Alcon OptiOne (not opti-free express), which also the KMart's American Value brand. KMart's American Value brand just released a No-Rub version of the MPS, and it's made by B&L, so it think it might be really close to ReNu Plus, not sure though. I don't think consumers know that contact lense supply requires FDA approval, so the generic store brands are actually made by the big 3, smaller companies can't afford the R&D and approval cost. In fact, if you compare the instruction panel, they virtually use the same wording as their expensive new brand siblings. I am using Costco's Kirkland Signature MPS, which is Allergan Complete, and I cleans and feels just like the Allergan brand. What's more, that stuff is sooo cheap, 3 of 16oz bottles is less than $8...
PS: MPS = multipurprose solution (industry lingo)
Allergan Complete is now made by AMO, Advanced Medical Optics, a spin-off of Allergan.
