Record label Sony Music has apologised for increasing the price of two Whitney Houston albums hours after her death on Saturday.
A spokesperson for the company called the move an "internal mistake due to an employee error", insisting the elevated prices remained in place for only a few hours.
"Whitney Houston product was mistakenly mispriced on the UK iTunes store on Sunday," Sony told Billboard, the US music industry newspaper.
"When discovered, the mistake was immediately corrected. We apologise for any offence caused."
Since the singer's death aged 48, her record sales have seen a major boost in the US and the UK.
Several of her songs are on course to re-enter the UK singles top 40 on Sunday with a greatest hits compilation heading for the top ten.
Whitney's cover of the Dolly Parton single, I Will Always Love You, is likely to reach the top 10 on Sunday.
