The Sale of Goods Act 1979 is a law that helps people who are buying things (like toys or clothes) from shops or other sellers. It says that when people buy something, it must be of good quality and work properly. This means that if you buy a toy and it stops working, the shop has to give you a new one or give you your money back.
The law also says that the things people sell must match the description they give. For example, if someone is selling a red balloon, but gives you a blue one instead, they have broken the law.
The Sale of Goods Act 1979 also gives people the right to take legal action against sellers who don't follow the rules. This means that you can ask a court to help you get your money back or make the seller give you a new item that works properly.
In summary, the Sale of Goods Act 1979 is a law that helps protect people who buy things from shops or other sellers. It ensures that what people buy is of good quality, works properly and matches the description given. If this doesn't happen, people have the right to take legal action.
