An ex-Primark worker has shared some insider secrets on how to get the best deals and avoid buying anything ‘gross.’ Joanna, who claims to have four years of experience on the shop floor, says that the first thing you should do is wash everything you buy as soon as you get home, as clothes on the racks get handled by a lot of people and might not be the freshest. Her other piece of advice is to go shopping on a Friday morning between 9am and 12pm, as fresh stock gets delivered on Thursday nights and hits the shelves overnight. She also claims that you can potentially snag a discount on items with minor imperfections, but it’s more likely to be around 10 percent.
