It seems that whilst bonuses to bankers are a hot potato - quite rightly so, say many - bonuses or incentives to consumers to promote products or services are fine.
A recent ruling by the European Court of Justice has said that national laws prohibiting the offering of any form of bonus to a consumer - money or a sample for example - are not legal in terms of the Unfair Commercial Practices Directive.
This because Article 4 of the Directive says that Member States cannot make stricter rules under what is a 'maximum harmonisation' directive, even if the purpose is to give consumers stronger protection.
Whilst a little known Austrian managed to start a World War, you can thank the rivalry between two Austrian daily newspapers and a 'footballer of the year' competition for the ruling.
So if you want to offer an extra inkjet cartridge, or a free draw for a pot of money - go ahead - you can.
