Osman sells football jerseys online at a shopping website called Murah.com. Osman put the description of the jersey which includes pictures, sizes, colours, jersey numbers, type of clothing material, and price. A buyer named Zulkarnain saw the advertisement on Murah.com and bought a "Ronaldo"original Adidas football jersey. As they normally retail at over RM500, he thought he had snapped up a bargain when he bought a pair at only RM150. When the parcel arrived 2 days later, he found out that the jersey was not the original "Ronaldo" but a fake one. He immediately contacted Osman on Murah.com to inform him about his suspicions and request a refund. Osman refused stating that the jersey was an original Adidas in the first place. The picture was just for advertisement purposes plus he never stated a money back guarantee policy. The buyer has already given a thorough consideration before clicking and buying the merchandise. By virtue of Sale of Goods Act 1957 and decided case law, state the issues and the validity of the above contract of sale.
