Four Amazon adverts for electronic devices have been banned for "misleading" customers over potential savings.
The adverts, all from July 2017, highlighted savings of up £300 compared with recommended retail prices (RRPs).
But complaints the RRPs were misleading and unsubstantiated were upheld by the Advertising Standards Authority.
Amazon admitted one advert was an "error" but said the other RRPs were in line with listings on other sites.
The adverts flagged up savings of £220 on an LG smart TV, £193 on a ViewSonic monitor, £300 on an MSI laptop and £185 on a Philips electronic toothbrush.
