Johnson&Johnson Gel de ducha hidrante / Fraudulent promotion

This product is a shower gel and not bad at all. Then I visited my corner shop here in Tenerife (Spain), I noticed that Johnson's had a promotion "+100 ml gratis". Of course I got one. At home I compared the bottle to my previous one with volume of 750 ml: the promotional one has the volume 650 ml + 100 ml!!! I never beliwed that a big, listed company could be that mean.

Now I have stopped to by ANY Johnson's products, I have spent hours in the shops telling this scam to customers, who have always left Johnson's product and replaced them with others. If you like to fight, replace at least every second Johson's product with another good alternative.
