Rights when buying goods
Goods must be of satisfactory quality, fit for purpose, and as described. You also have a right that goods will match any sample or model shown. If goods fail to meet these standards, you have a short-term right to reject (within 30 days), followed by the right to request a repair or replacement, and ultimately a right to a price reduction or final rejection if repair or replacement fails.
