We only have two people in this household, so if there is a choice between the expensive brand in small bottles versus the cheaper brand in large bottles, we generally choose the expensive brand in small bottles (with coupons and 75% off, of course).
It troubles me how many times we have brought off-brand beauty stuff and only have it spoil before we finish the stuff. It also troubles me how much more we are using to "use up" the cheap stuff. It seems the bigger the bottles are, the bigger the portions would be.
I ordered this a month ago. It is quite expensive but I loved everything in the package and the package would last me four months because everything is so super concentratd. They were nothing like what I have used before. They were 100 times better than what I am used to.
