Jenny received a circular from Beauty and the Beast Hair Salon advertising massages and manicures for $10. 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 Jenny arrived at the salon she was told that there had been a mistake on the circular and it should have said $100. The manager of the salon explained that this was still a good price because normally a massage and manicure would have cost $150. Jenny was furious, as it had taken her 30 minutes to get to the shop by car and if she had known it would cost $100, she would never have made the booking. Advise Jenny. Would your advice have been any different if Jenny had the massage and manicure before being told that the cost was $100? Would she have to pay the full price?
