Reporting a wrong figure
Corrections take priority. Include the model number and, where the page shows one, the registration number (in the form ACW1626), which identifies the exact record. Prices change after their check date and are not corrected by hand; specification errors are checked against the source and corrected.
Retailers and manufacturers
Every model registered in the GEMS database is included automatically; there is no listing process and no fee. Price feeds and specification sources that would improve coverage or accuracy can be sent to the same address.
