Of those likely to shop in the sales, 48% are planning on buying electronics, with laptops, tablets, phones and TVs featuring heavily, the research shows.
“Three out of five sales shoppers say they’re motivated by discounts – this is why it’s so important that retailers are honest and transparent about reductions.
"You can’t discount a product from a price it was never on sale for, or hike the price up for a couple of days so you can advertise a discount based on that artificially high price.
"The CCPC is actively monitoring online and instore discounts to ensure that consumers are not being misled.”
