Bests & Worsts Reviews from Amazon

I purchased this because the price was so much better than what I pay for it in the store. The packaging looked fine but as soon as I pumped some out of the bottle, I noticed it is off white rather than the yellow color that my other two bottles were. I opened it up and looked inside the bottle and noticed that it is only half full. I think maybe there was some of the original serum in there and mixed with some other lotion. I won't be buying from Amazon again and really disappointed because I loved the price!
