Due to petrol prices increasing dramatically in recent months due to the Conflict in Ukraine, Ricardo has opted to sell his limited edition Jaguar XF351, and is thinking buying a smaller vehicle. Ricardo places an advertisement in his car window on 30th August stating: 'Jaguar XF351' excellent condition, one owner N$325,000 or nearest offer. Please contact Ricardo on +264 81 333 3214 (evening) or +264 61 777 8536 (during office hours 9:00 -17:00).' Zarkov (Ricardo's neighbour) on seeing the advert earlier that day, decides to contact Ricardo that evening, and arranges to inspect the vehicle. After inspecting the vehicle Zarkov states that he will contact him, if he's still interested. On 3rd September, Martha calls Ricardo's mobile number after inspecting the vehicle (the previous day), and offers N$324,500. Ricardo is delighted and says 'how about N$324, 750?' Martha states that she will need to discuss this with her husband, Ricardo tells her to call back at 6:00 pm. Martha contacts Ricardo on his mobile phone at 7.30pm; however the phone is switched off. As there is no facility to leave a message, Martha tries his work number the following day, however Ricardo is at a conference so she leaves a message on his answering machine, stating that she definitely wants the Jaguar XF351 for N$324,750. Ricardo doesn't return to his desk until late that afternoon and fails to listen to his answering machine that day. Martha then tries his mobile in the evening but it's still switched off. Stewart, a dedicated car dealer, contacts Ricardo the next day (4th September), on his mobile phone, stating that he's really interested in the vehicle, and arranges to meet Ricardo during his lunch break to inspect the vehicle. Ricardo meets Stewart, and accepts an offer of N$347,000 from Stewart. Ricardo is delighted with the sale and decides to purchase a pair of Gucci shoes. When he enters the shop, he sees a price tag by a pair of Gucci shoes for N$12189. He has always wanted a pair but could never afford them, so thinking that the shoes are on sale, attempts to purchase them. When he gets to the till point, the cashier scans the barcode on the box and informs Ricardo that shoes are N$121210. Ricardo refuses to pay N$121210, and demands he should have the shoes for N$12189. Zarkov and Martha contact Ricardo the next day (5th September) demanding the vehicle for the advertised price. Advise Ricardo.
