Hi all,
Quote from Which?
"A sale must be genuine
If a shop is advertising a sale it has to follow government guidelines in order to ensure it's genuine. There are three key things to look out for:
•Before reducing prices in a sale, items must have been sold at the higher price for 28 consecutive days in that store immediately before the sale, unless a sign explains the terms of the offer
•Items shouldn't be on offer at the sale price for longer than being sold at the higher price unless the shop displays a sign explaining how the sale differs from these rules or, if something is going out of date
•The original price must be clearly displayed along with the sale price. A sign shouldn't just say 'sale £15' – it must say something like 'was £50, sale price £15'
"
Hope this helps.
