Lushani received a circular from "Kesha Beauty Hair Salon" advertising hair-cuts and wash for Rs100. Realising that this was an exceptionally good deal, but not surprised because she knew that they had only just opened and were running a number of good opening specials, she rang and made a booking. When Lushani arrived at the salon she was told that there had been a mistake on the circular and it should have said Rs1000. The manager of the salon explained that this was still a good price because normally a hair-cut and wash would have cost Rs1500. Lushani was furious, as it had taken her 30 minutes to get to the shop by bus and if she had known it would cost Rs1000, she would never have made the booking.

a. Advise Lushani.

b. Would your advice have been any different if Lushani had the hair-cut and wash before being told that the cost was Rs1000? Would she have to pay the full price?
