FIRMS who failed to be up front about delivery charges to Moray customers have been issued with an enforcement notice.
The Committees of Advertising Practice (CAP) have handed the notices on advertised delivery and surcharges to over 120 companies.
Moray MSP Richard Lochhead wrote to the Advertising Standards Authority (ASA) in January with a dossier of firms who had failed to be up front on charges to parts of Scotland.
MP Douglas Ross has also been campaigning for action raising the issue with Prime Minister Theresa May and requesting that the Scottish Affairs Committee carry out an inquiry, which is now underway.
In many cases free delivery was advertised with a late additional charge in the online order process.
The enforcement notice, which was issued yesterday by CAP, demands "prompt action" from those companies which appear to be misleading customers with the threat of enforcement action, including legal measures, if firms fail to comply by the May 31 deadline.
The MSP has welcomed the action from the watchdog and described it as a "significant first step" in the crackdown on unfair delivery charges.
He said: "I'm sure that people living across Scotland will be pleased to see companies taken to task and told to stop advertising free delivery when in many cases, for many customers, the reality is very different.
"It is now incumbent upon those companies who are failing to be upfront with consumers to sit up, take notice and change their practices. I hope they respond swiftly to this very clear shot across their bows."
The campaign to highlight the issues around unfair delivery charges has seen action from national companies including Amazon.
Commenting on the most recent announcement, Moray MP Douglas Ross said: ""The new rules will ensure delivery charges are clear and transparent for consumers and I welcome that companies will now face penalties for misleading consumers when advertising their delivery charges.
"Although this is another positive step in the campaign for fairer delivery charges, more still needs to be done to end the scandal of this postcode lottery on delivery charges."
