Winehouse's albums rocketed up the chart following her death on July 23 last year, with 'Back to Black' hitting the top spot a week after her passing, reported Contactmusic.
Now chart bosses have marked a year since her death by revealing Winehouse's fans bought 1.2 million copies of her three albums, as well as 500,000 of her singles, in the past year.
"Many of us will remember where we were when we heard the terrible news about Amy a year ago. And the fact that music fans have, since then, bought her music in such large numbers demonstrates just how highly she was regarded by the great British public," said Official Charts Company managing director Martin Talbot.
The singer was found dead at her home in London after suffering alcohol intoxication.
