Sports Direct’s pricing could be misleading shoppers into thinking they are getting a better deal than they really are, consumer group Which? has said.

The watchdog has reported Sports Direct to the Competition and Markets Authority (CMA) following tip-offs over the retail giant’s use of Recommended Retail Prices (RRPs).

Sports Direct commonly prices its products with a comparative RRP figure to indicate it is offering customers a cheaper deal.

But Which? said its researchers could not find some items sold at Sports Direct’s stated RRP price anywhere else online.

As well as using RRPs as reference prices, the chain also uses terms such as Manufacturer Suggested Retail Price (MSRP) or Suggested Retail Price (SRP), which the watchdog believed would also be interpreted by consumers as being the same as an RRP.

Which? said it was tipped off about “suspicious” RRPs by Which? readers, and proceeded to look at the pricing of 160 popular products on SportsDirect.com.

Overall, for 58 of the 160 products investigated, Which? found no retailer selling them online at or above the Sports Direct reference price.

For a further 53, Which? did find the product at or above the reference price at another retailer, but in each case that retailer was part of the Frasers Group, Sports Direct’s owner. All of these items were Frasers Group own-brand products.

Mike Ashley’s Frasers Group has a large portfolio of brands under its umbrella including Jack Wills, Slazenger, Everlast and Lonsdale.

Frasers Group also owns various retailers such as USC, Studio, and Get the Label, which sometimes appeared to be the only sellers of these particular brands, Which? said.

Which? found a Jack Wills Hunston graphic logo hoodie in green for £24 at Sports Direct, with the item advertised as having a Manufacturer Suggested Retail Price (MSRP) of £54.99.

Which? researchers could not find the item sold or supplied by anyone other than Frasers Group retailers.

It was £40 on Amazon – which is supplied by Sports Direct – but all the other retailers sold it at £24.

Which? also found a pair of Slazenger men’s tennis shoes selling at Sports Direct for £32.99 – nearly half the MSRP of £64.99.

Which? found the trainers sold on eight other websites, but the owner or seller was always part of the parent company.

Seven retailers sold them for £32.99, or in one case £33. Only one retailer, Slazenger itself, sold them at the MSRP.

A Whitaker Somerfield long sleeve base layer for equestrian sports was also selling at Sports Direct at £8 with an RRP of £35.
