I went with my frugal friend to the store to buy some shampoo,of course you the bottle thinking better deal..wrong..my friend says he always buys the sachets(normally samples in many countries) cause there cheaper per ounce/gr ounce..He said do the math and I did and he was right.. I still bought the bottle.For the hell of it i tryed it with Coke Cola..,2 ltr versus 1.5 ltr and the 1.5 was cheaper...Automatic opposite in the USA and other countries I presume...Just a thought for you frugal guys...hahaha
