i am writting to you as a professional stylist, and a redken master colorist. the prices on here do not reflect the prices that i pay(wholesale), so i would be very careful of who i buy from and how much i pay. For exaple a liter of CLEAR runs about 37.00 us dollars, each color runs about 5.26, and a liter  of  processing solution is close to 6.00 dollars., so if some one is selling for less i would assume that the product is either old, damaged or stolen.good luck!
