Primark has urged consumers not to buy its products online after its Disney and Harry Potter ranges were found listed for sale by Amazon third-party vendors.
Scalpers buying the licensed lines in bulk are charging more than twice the amount they paid in-store, and in some cases more than four-times the price Primark is asking.
The fast-fashion retailer does not have an online store, and took to Twitter to warn customers they would find the clothes and accessories cheaper by visiting one of its nearly 200 UK stores.
“We do not have a commercial partnership with Amazon and any Primark products which appear on the site are being re-sold by third-parties, at higher prices. We encourage our customers to visit us in our stores to find the best value,” the tweet read.
Some third-party vendors are even masquerading as the discount retailer, using the Primark brand name in a bid to dupe shoppers into thinking it's an official account.
Primark items listed on Amazon include licensed loungewear, pyjamas, and homewares such as Friends fridge magnets and a popular Beauty and the Beast mug – that particular item, The Sun points out, is going for more than five times the £5 RRP.
The BBC also found dozens of Primark items on Ebay with a mark up of “between 50-75 per cent”.
Last month CNBC discovered Amazon was allowing third-party vendors to list toys on the site without providing documents to the prove the products were safe. Sellers said they were only asked to provide the necessary safety documentation weeks after the listings originally went live.
Amazon responded by saying that all goods sold on the platform “must comply with applicable laws and regulations”.
The online marketplace has come under fire for not being able to keep up with the scale of its operation.
Marketplace Pulse estimates that two new sellers sign up to Amazon every minute.
