New and stronger consumer rights in the UK will come into force on 1 October.
The Consumer Rights Act will enable shoppers to demand refunds if the goods they buy are faulty.
The Act covers everything from buying online and in shops to consumer contracts for ongoing services.
Retailers are now obliged to make a full refund on faulty items within 30 days.
Goods most frequently faulty include clothing, electronic goods such as phones, and used cars.
Under previous legislations, retailers were able to offer to repair the items, but now people are within their rights to ask for replacements or refunds.
This is the first time a statutory time frame has been introduced for refunds for faulty items. It also for the first time covers digital content, including music and video download services such as Spotify or Netflix.
Such content must be of satisfactory quality, fit for a particular purpose and as described by the seller. If not, the consumer is entitled to a refund.
Delivery of goods must be accomplished within 30 days, or on the date that has been agreed, or the buyer can get a full refund.
All contracts must state clearly the main elements of the deal and show the price in a transparent and prominent way. Charges cannot be hidden in the small print of terms and conditions, and these terms must be in plain and intelligible language.
The Act also seeks to ensure that tradesmen doing work, such as fitting kitchens or bathrooms, deliver the service and quality they promised.
The new rules are compulsory, and retailers face prosecution if they do not abide by them. They are not, however, retrospective.
