Karen is an avid dog fancier. She has a number of dogs that she grooms and trains for dog shows. Her dogs have done quite well in dog shows and she has had several 'best in show' awards. Her prize dog is Fifi, a little Shih Tzu. Fifi has won numerous awards. Karen wishes to enter Fifi in the upcoming annual town show and Karen believes that Fifi has good prospects of winning the best in show award that comes with prize money of $10,000.00. Last year, Fifi actually won the best in show award. On Wednesday, a few days before the show, Karen decides to take Fifi to her regular dog groomer, Fiona. Fiona is also one of the sponsors of the annual dog show. Fiona has a special package that she has advertised on her website as follows:

"Special Wednesday Package: Bring in your pooch for a pamper session! For $100 your dog will get a luxurious bath, blow dry, brush, haircut, nail cut and teeth clean. Normally this will cost you $200! Hurry. This offer is limited to the first 5 customers!"

Karen makes sure that she is the first customer waiting when Fiona opens her grooming salon at 9am. Karen mentions the web page special and asks for the Special Wednesday Package. This Photo by Unknown Author is licensed under CC BY-SA 3 Fiona tells her that unfortunately, that special applied to the Wednesday of the week before and does not apply to this Wednesday. In any case, says Fiona, the web promotion is just 'sales talk' and is not really an offer. Fiona says that, because Karen is such a loyal customer, she will do the package for $150.

- is that advert an offer? what relevant case would be able to support it.
