Merchants of Venus is a romantic comedy film starring British actors Michael York and Prunella Gee. It was written and directed by Len Richmond, writer of the award-winning British comedy series Agony and the less successful Split Ends. The film was released in the US in March 1998 and was given a straight to DVD release in the UK on 1 September 2001, renamed as A Dirty Little Business. In some countries, it was released under the title Good Vibrations.

The film is certified as a 15, runs for 74 minutes, and original music is provided by the band Erasure who performed the track Love Affair. The band's lead singer Andy Bell has a small role in the movie as the director of an adult film that Gee's character is playing in.

The movie was actually filmed in Len Richmond's mother's own sex toy factory in Los Angeles.
